The Prophet (saws) said: The best things with which grey hair are changed are henna and katam.

`Umar used to admit me (into his house) along with the old men who had fought in the Badr battle. Some of them said (to `Umar), "Why do you allow this young man to enter with us, while we have sons of his own age? " `Umar said, "You know what person he is." One day `Umar called them and called me along with them, I had thought he called me on that day to show them something about me (i.e. my knowledge). `Umar asked them, "What do you say about (the Sura): "When comes the help of Allah and the Conquest (of Mecca) And you see mankind entering the Religion of Allah (i.e. Islam) in crowds. 'So celebrate the Praises Of your Lord and ask for His forgiveness, Truly, He is the One Who accepts repentance and forgives." (110.1-3) Some of them replied, "We are ordered to praise Allah and repent to Him if we are helped and granted victory." Some said, "We do not know." Others kept quiet. `Umar then said to me, "Do you say similarly?" I said, "No." `Umar said "What do you say then?" I said, "This Verse indicates the approaching of the death of Allah's Apostle of which Allah informed him. When comes the help of Allah and the Conquest, i.e. the Conquest of Mecca, that will be the sign of your Prophet's) approaching death, so testify the uniqueness of your Lord (i.e. Allah) and praise Him and repent to Him as He is ready to forgive." On that, `Umar said, "I do not know about it anything other than what you know."

I relate the traditions of Allah's Apostle to you for I would rather fall from the sky than attribute something to him falsely. But when I tell you a thing which is between you and me, then no doubt, war is guile. I heard Allah's Apostle saying, "In the last days of this world there will appear some young foolish people who will use (in their claim) the best speech of all people (i.e. the Qur'an) and they will abandon Islam as an arrow going through the game. Their belief will not go beyond their throats (i.e. they will have practically no belief), so wherever you meet them, kill them, for he who kills them shall get a reward on the Day of Resurrection."

Hind bint `Utba bin Rabi`a said, "O Allah 's Apostle! (Before I embraced Islam), there was no family on the surface of the earth, I wish to have degraded more than I did your family. But today there is no family whom I wish to have honored more than I did yours." Allah's Apostle said, "I thought similarly, by Him in Whose Hand Muhammad's soul is!" Hind said, "O Allah's Apostle! (My husband) Abu Sufyan is a miser. Is it sinful of me to feed my children from his property?" The Prophet said, "No, unless you take it for your needs what is just and reasonable."

Abu Sufyan bin Harb informed me that Heraclius had sent a messenger to him while he had been accompanying a caravan from Quraish. They were merchants doing business in Sham (Syria, Palestine, Lebanon and Jordan), at the time when Allah's Apostle had truce with Abu Sufyan and Quraish infidels. So Abu Sufyan and his companions went to Heraclius at Ilya (Jerusalem). Heraclius called them in the court and he had all the senior Roman dignitaries around him. He called for his translator who, translating Heraclius's question said to them, "Who amongst you is closely related to that man who claims to be a Prophet?" Abu Sufyan replied, "I am the nearest relative to him (amongst the group)."

Heraclius said, "Bring him (Abu Sufyan) close to me and make his companions stand behind him." Abu Sufyan added, Heraclius told his translator to tell my companions that he wanted to put some questions to me regarding that man (The Prophet) and that if I told a lie they (my companions) should contradict me." Abu Sufyan added, "By Allah! Had I not been afraid of my companions labeling me a liar, I would not have spoken the truth about the Prophet. The first question he asked me about him was:

'What is his family status amongst you?'

I replied, 'He belongs to a good (noble) family amongst us.'

Heraclius further asked, 'Has anybody amongst you ever claimed the same (i.e. to be a Prophet) before him?'

I replied, 'No.'

He said, 'Was anybody amongst his ancestors a king?'

I replied, 'No.'

Heraclius asked, 'Do the nobles or the poor follow him?'

I replied, 'It is the poor who follow him.'

He said, 'Are his followers increasing decreasing (day by day)?'

I replied, 'They are increasing.'

He then asked, 'Does anybody amongst those who embrace his religion become displeased and renounce the religion afterwards?'

I replied, 'No.'

Heraclius said, 'Have you ever accused him of telling lies before his claim (to be a Prophet)?'

I replied, 'No. '

Heraclius said, 'Does he break his promises?'

I replied, 'No. We are at truce with him but we do not know what he will do in it.' I could not find opportunity to say anything against him except that.

Heraclius asked, 'Have you ever had a war with him?'

I replied, 'Yes.'

Then he said, 'What was the outcome of the battles?'

I replied, 'Sometimes he was victorious and sometimes we.'

Heraclius said, 'What does he order you to do?'

I said, 'He tells us to worship Allah and Allah alone and not to worship anything along with Him, and to renounce all that our ancestors had said. He orders us to pray, to speak the truth, to be chaste and to keep good relations with our Kith and kin.'

Heraclius asked the translator to convey to me the following, I asked you about his family and your reply was that he belonged to a very noble family. In fact all the Apostles come from noble families amongst their respective peoples. I questioned you whether anybody else amongst you claimed such a thing, your reply was in the negative. If the answer had been in the affirmative, I would have thought that this man was following the previous man's statement. Then I asked you whether anyone of his ancestors was a king. Your reply was in the negative, and if it had been in the affirmative, I would have thought that this man wanted to take back his ancestral kingdom.

I further asked whether he was ever accused of telling lies before he said what he said, and your reply was in the negative. So I wondered how a person who does not tell a lie about others could ever tell a lie about Allah. I, then asked you whether the rich people followed him or the poor. You replied that it was the poor who followed him. And in fact all the Apostle have been followed by this very class of people. Then I asked you whether his followers were increasing or decreasing. You replied that they were increasing, and in fact this is the way of true faith, till it is complete in all respects. I further asked you whether there was anybody, who, after embracing his religion, became displeased and discarded his religion. Your reply was in the negative, and in fact this is (the sign of) true faith, when its delight enters the hearts and mixes with them completely. I asked you whether he had ever betrayed. You replied in the negative and likewise the Apostles never betray. Then I asked you what he ordered you to do. You replied that he ordered you to worship Allah and Allah alone and not to worship any thing along with Him and forbade you to worship idols and ordered you to pray, to speak the truth and to be chaste. If what you have said is true, he will very soon occupy this place underneath my feet and I knew it (from the scriptures) that he was going to appear but I did not know that he would be from you, and if I could reach him definitely, I would go immediately to meet him and if I were with him, I would certainly wash his feet.' Heraclius then asked for the letter addressed by Allah's Apostle

which was delivered by Dihya to the Governor of Busra, who forwarded it to Heraclius to read. The contents of the letter were as follows: "In the name of Allah the Beneficent, the Merciful (This letter is) from Muhammad the slave of Allah and His Apostle to Heraclius the ruler of Byzantine. Peace be upon him, who follows the right path. Furthermore I invite you to Islam, and if you become a Muslim you will be safe, and Allah will double your reward, and if you reject this invitation of Islam you will be committing a sin of Arisiyin (tillers, farmers i.e. your people). And (Allah's Statement:)

'O people of the scripture! Come to a word common to you and us that we worship none but Allah and that we associate nothing in worship with Him, and that none of us shall take others as Lords beside Allah. Then, if they turn away, say: Bear witness that we are Muslims (those who have surrendered to Allah).' (3:64).

Abu Sufyan then added, "When Heraclius had finished his speech and had read the letter, there was a great hue and cry in the Royal Court. So we were turned out of the court. I told my companions that the question of Ibn-Abi-Kabsha) (the Prophet Muhammad) has become so prominent that even the King of Bani Al-Asfar (Byzantine) is afraid of him. Then I started to become sure that he (the Prophet) would be the conqueror in the near future till I embraced Islam (i.e. Allah guided me to it)."

The sub narrator adds, "Ibn An-Natur was the Governor of llya' (Jerusalem) and Heraclius was the head of the Christians of Sham. Ibn An-Natur narrates that once while Heraclius was visiting ilya' (Jerusalem), he got up in the morning with a sad mood. Some of his priests asked him why he was in that mood? Heraclius was a foreteller and an astrologer. He replied, 'At night when I looked at the stars, I saw that the leader of those who practice circumcision had appeared (become the conqueror). Who are they who practice circumcision?' The people replied, 'Except the Jews nobody practices circumcision, so you should not be afraid of them (Jews).

'Just Issue orders to kill every Jew present in the country.'

While they were discussing it, a messenger sent by the king of Ghassan to convey the news of Allah's Apostle to Heraclius was brought in. Having heard the news, he (Heraclius) ordered the people to go and see whether the messenger of Ghassan was circumcised. The people, after seeing him, told Heraclius that he was circumcised. Heraclius then asked him about the Arabs. The messenger replied, 'Arabs also practice circumcision.'

(After hearing that) Heraclius remarked that sovereignty of the 'Arabs had appeared. Heraclius then wrote a letter to his friend in Rome who was as good as Heraclius in knowledge. Heraclius then left for Homs. (a town in Syrian and stayed there till he received the reply of his letter from his friend who agreed with him in his opinion about the emergence of the Prophet and the fact that he was a Prophet. On that Heraclius invited all the heads of the Byzantines to assemble in his palace at Homs. When they assembled, he ordered that all the doors of his palace be closed. Then he came out and said, 'O Byzantines! If success is your desire and if you seek right guidance and want your empire to remain then give a pledge of allegiance to this Prophet (i.e. embrace Islam).'

(On hearing the views of Heraclius) the people ran towards the gates of the palace like onagers but found the doors closed. Heraclius realized their hatred towards Islam and when he lost the hope of their embracing Islam, he ordered that they should be brought back in audience.

(When they returned) he said, 'What already said was just to test the strength of your conviction and I have seen it.' The people prostrated before him and became pleased with him, and this was the end of Heraclius's story (in connection with his faith).

The funeral prayer should be offered for every child even if he were the son of a prostitute as he was born with a true faith of Islam (i.e. to worship none but Allah Alone). If his parents are Muslims, particularly the father, even if his mother were a non-Muslim, and if he after the delivery cries (even once) before his death (i.e. born alive) then the funeral prayer must be offered. And if the child does not cry after his delivery (i.e. born dead) then his funeral prayer should not be offered, and he will be considered as a miscarriage. Abu Huraira, narrated that the Prophet said, "Every child is born with a true faith (i.e. to worship none but Allah Alone) but his parents convert him to Judaism or to Christianity or to Magainism, as an animal delivers a perfect baby animal. Do you find it mutilated?" Then Abu Huraira recited the holy verses: 'The pure Allah's Islamic nature (true faith i.e. to worship none but Allah Alone), with which He has created human beings.' " (30.30).

We came to the Prophet and stayed with him for twenty days and nights. We were all young and of about the same age. The Prophet was very kind and merciful. When he realized our longing for our families, he asked about our homes and the people there and we told him. Then he asked us to go back to our families and stay with them and teach them (the religion) and to order them to do good things. He also mentioned some other things which I have (remembered or [??] ) forgotten. The Prophet then added, "Pray as you have seen me praying and when it is the time for the prayer one of you should pronounce the Adhan and the oldest of you should lead the prayer.

(the clerk of Al-Mughira bin Shu`ba) Muawiya wrote to Al-Mughira: "Write to me a narration you have heard from Allah's Apostle." So Al-Mughira wrote to him, "I heard him saying the following after each prayer: 'La ilaha illal-lahu wahdahu la sharika lahu, lahu-l-mulk wa lahuI-hamd, wa huwa 'ala kulli Shai-in qadir.' He also used to forbid idle talk, asking too many questions (in religion), wasting money, preventing what should be given, and asking others for something (except in great need), being undutiful to mothers, and burying one's little daughters (alive).

I was sitting in a gathering in which there was Sa`d bin Malik and Ibn `Umar. `Abdullah bin Salam passed in front of them and they said, "This man is from the people of Paradise." I said to `Abdullah bin Salam, "They said so-and-so." He replied, "Subhan Allah! They ought not to have said things of which they have no knowledge, but I saw (in a dream) that a post was fixed in a green garden. At the top of the post there was a handhold and below it there was a servant. I was asked to climb (the post). So I climbed it till I got hold of the handhold." Then I narrated this dream to Allah's Apostle. Allah's Apostle said, "`Abdullah will die while still holding the firm reliable handhold (i.e., Islam).

I asked Abu Wail, "Did you witness the battle of Siffin between `Ali and Muawiya?" He said, "Yes," and added, "Then I heard Sahl bin Hunaif saying, 'O people! Blame your personal opinions in your religion. No doubt, I remember myself on the day of Abi Jandal; if I had the power to refuse the order of Allah's Apostle, I would have refused it. We have never put our swords on our shoulders to get involved in a situation that might have been horrible for us, but those swords brought us to victory and peace, except this present situation.' " Abu Wail said, "I witnessed the battle of Siffin, and how nasty Siffin was!"

I saw the drinking bowl of the Prophet with Anas bin Malik, and it had been broken, and he had mended it with silver plates. That drinking bowl was quite wide and made of Nadar wood, Anas said, "I gave water to the Prophet in that bowl more than so-and-so (for a long period)." Ibn Seereen said: Around that bowl there was an iron ring, and Anas wanted to replace it with a silver or gold ring, but Abu Talha said to him, "Do not change a thing that Allah's Apostle has made." So Anas left it as it was.

Once we were traveling with the Prophet and we carried on traveling till the last part of the night and then we (halted at a place) and slept (deeply). There is nothing sweeter than sleep for a traveler in the last part of the night. So it was only the heat of the sun that made us to wake up and the first to wake up was so and so, then so and so and then so and so (the narrator `Auf said that Abu Raja' had told him their names but he had forgotten them) and the fourth person to wake up was `Umar bin Al- Khattab. And whenever the Prophet used to sleep, nobody would wake up him till he himself used to get up as we did not know what was happening (being revealed) to him in his sleep. So, `Umar got up and saw the condition of the people, and he was a strict man, so he said, "Allahu Akbar" and raised his voice with Takbir, and kept on saying loudly till the Prophet got up because of it. When he got up, the people informed him about what had happened to them. He said, "There is no harm (or it will not be harmful). Depart!" So they departed from that place, and after covering some distance the Prophet stopped and asked for some water to perform the ablution. So he performed the ablution and the call for the prayer was pronounced and he led the people in prayer. After he finished from the prayer, he saw a man sitting aloof who had not prayed with the people. He asked, "O so and so! What has prevented you from praying with us?" He replied, "I am Junub and there is no water. " The Prophet said, "Perform Tayammum with (clean) earth and that is sufficient for you." Then the Prophet proceeded on and the people complained to him of thirst. Thereupon he got down and called a person (the narrator `Auf added that Abu Raja' had named him but he had forgotten) and `Ali, and ordered them to go and bring water. So they went in search of water and met a woman who was sitting on her camel between two bags of water. They asked, "Where can we find water?" She replied, "I was there (at the place of water) this hour yesterday and my people are behind me." They requested her to accompany them. She asked, "Where?" They said, "To Allah's Apostle ." She said, "Do you mean the man who is called the Sabi, (with a new religion)?" They replied, "Yes, the same person. So come along." They brought her to the Prophet and narrated the whole story. He said, "Help her to dismount." The Prophet asked for a pot, then he opened the mouths of the bags and poured some water into the pot. Then he closed the big openings of the bags and opened the small ones and the people were called upon to drink and water their animals. So they all watered their animals and they (too) all quenched their thirst and also gave water to others and last of all the Prophet gave a pot full of water to the person who was Junub and told him to pour it over his body. The woman was standing and watching all that which they were doing with her water. By Allah, when her water bags were returned the looked like as if they were more full (of water) than they had been before (Miracle of Allah's Apostle) Then the Prophet ordered us to collect something for her; so dates, flour and Sawiq were collected which amounted to a good meal that was put in a piece of cloth. She was helped to ride on her camel and that cloth full of foodstuff was also placed in front of her and then the Prophet said to her, "We have not taken your water but Allah has given water to us." She returned home late. Her relatives asked her: "O so and so what has delayed you?" She said, "A strange thing! Two men met me and took me to the man who is called the Sabi' and he did such and such a thing. By Allah, he is either the greatest magician between this and this (gesturing with her index and middle fingers raising them towards the sky indicating the heaven and the earth) or he is Allah's true Apostle." Afterwards the Muslims used to attack the pagans around her abode but never touched her village. One day she said to her people, "I think that these people leave you purposely. Have you got any inclination to Islam?" They obeyed her and all of them embraced Islam. Abu `Abdullah said: The word Saba'a means "The one who has deserted his old religion and embraced a new religion." Abul 'Ailya [??] said, "The S`Abis are a sect of people of the Scripture who recite the Book of Psalms."

I heard Allah's Apostle saying, 'Both legal and illegal things are evident but in between them there are doubtful (suspicious) things and most of the people have no knowledge about them. So whoever saves himself from these suspicious things saves his religion and his honor. And whoever indulges in these suspicious things is like a shepherd who grazes (his animals) near the Hima (private pasture) of someone else and at any moment he is liable to get in it. (O people!) Beware! Every king has a Hima and the Hima of Allah on the earth is His illegal (forbidden) things. Beware! There is a piece of flesh in the body if it becomes good (reformed) the whole body becomes good but if it gets spoilt the whole body gets spoilt and that is the heart.

Anas said, "Some people of `Ukl or `Uraina tribe came to Medina and its climate did not suit them. So the Prophet ordered them to go to the herd of (Milch) camels and to drink their milk and urine (as a medicine). So they went as directed and after they became healthy, they killed the shepherd of the Prophet and drove away all the camels. The news reached the Prophet early in the morning and he sent (men) in their pursuit and they were captured and brought at noon. He then ordered to cut their hands and feet (and it was done), and their eyes were branded with heated pieces of iron, They were put in 'Al-Harra' and when they asked for water, no water was given to them." Abu Qilaba said, "Those people committed theft and murder, became infidels after embracing Islam and fought against Allah and His Apostle ."

The Prophet and Abu Bakr employed a (pagan) man from the tribe of Bani Ad-Dail and the tribe of Bani 'Abu bin `Adi as a guide. He was an expert guide and he broke the oath contract which he had to abide by with the tribe of Al-`Asi bin Wail and he was on the religion of Quraish pagans. The Prophet and Abu Bakr had confidence in him and gave him their riding camels and told him to bring them to the Cave of Thaur after three days. So, he brought them their two riding camels after three days and both of them (The Prophet and Abu Bakr) set out accompanied by 'Amir bin Fuhaira and the Dili guide who guided them below Mecca along the road leading to the sea-shore.

That while he was with a delegation from Quraish to Muawiya, the latter heard the news that `Abdullah bin `Amr bin Al-`As said that there would be a king from the tribe of Qahtan. On that Muawiya became angry, got up and then praised Allah as He deserved, and said, "Now then, I have heard that some men amongst you narrate things which are neither in the Holy Book, nor have been told by Allah's Apostle. Those men are the ignorant amongst you. Beware of such hopes as make the people go astray, for I heard Allah's Apostle saying, 'Authority of ruling will remain with Quraish, and whoever bears hostility to them, Allah will destroy him as long as they abide by the laws of the religion.' "

Some people (i.e. the Jews of Bani bin Quraiza) agreed to accept the verdict of Sa`d bin Mu`adh so the Prophet sent for him (i.e. Sa`d bin Mu`adh). He came riding a donkey, and when he approached the Mosque, the Prophet said, "Get up for the best amongst you." or said, "Get up for your chief." Then the Prophet said, "O Sa`d! These people have agreed to accept your verdict." Sa`d said, "I judge that their warriors should be killed and their children and women should be taken as captives." The Prophet said, "You have given a judgment similar to Allah's Judgment (or the King's judgment).

Allah's Apostle sent us towards Al-Huruqa, and in the morning we attacked them and defeated them. I and an Ansari man followed a man from among them and when we took him over, he said, "La ilaha illal-Lah." On hearing that, the Ansari man stopped, but I killed him by stabbing him with my spear. When we returned, the Prophet came to know about that and he said, "O Usama! Did you kill him after he had said "La ilaha ilal-Lah?" I said, "But he said so only to save himself." The Prophet kept on repeating that so often that I wished I had not embraced Islam before that day.

When Abu Talib's death approached, the Prophet went to him while Abu Jahl and `Abdullah bin Abi Umaiya were present with him. The Prophet said, "O uncle, say: None has the right to be worshipped except Allah, so that I may argue for your case with it before Allah." On that, Abu Jahl and `Abdullah bin Abu Umaiya said, "O Abu Talib! Do you want to renounce `Abdul Muttalib's religion?" Then the Prophet said, "I will keep on asking (Allah for) forgiveness for you unless I am forbidden to do so." Then there was revealed:-- 'It is not fitting for the Prophet and those who believe that they should invoke (Allah) for forgiveness for pagans even though they be of kin, after it has become clear to them that they are companions of the Fire.' (9.113)

My father, seeing a silken cloak being sold, said, "O Allah's Apostle! Buy this and wear it on Fridays and when the foreign delegates pay a visit to you." He said, "This is worn only by that person who will have no share in the Hereafter." Later a few silken cloaks were given to the Prophet as a gift, and he sent one of those cloaks to `Umar. `Umar said (to the Prophet), "How can I wear it while you have said about it what you said?" The Prophet said, "I did not give it to you to wear but to sell or to give to someone else to wear." So `Umar sent it to his (pagan) brother who was from the inhabitants of Mecca before he (`Umar's brother) embraced Islam.

Whenever I tell you a narration from Allah's Apostle, by Allah, I would rather fall down from the sky than ascribe a false statement to him, but if I tell you something between me and you (not a Hadith) then it was indeed a trick (i.e., I may say things just to cheat my enemy). No doubt I heard Allah's Apostle saying, "During the last days there will appear some young foolish people who will say the best words but their faith will not go beyond their throats (i.e. they will have no faith) and will go out from (leave) their religion as an arrow goes out of the game. So, where-ever you find them, kill them, for who-ever kills them shall have reward on the Day of Resurrection."

`Abdullah bin `Umar came to us and we hoped that he would narrate to us a good Hadith. But before we asked him, a man got up and said to him, "O Abu `Abdur-Rahman! Narrate to us about the battles during the time of the afflictions, as Allah says:-- 'And fight them until there is no more afflictions (i.e. no more worshipping of others besides Allah).'" (2.193) Ibn `Umar said (to the man), "Do you know what is meant by afflictions? Let your mother bereave you! Muhammad used to fight against the pagans, for a Muslim was put to trial in his religion (The pagans will either kill him or chain him as a captive). His fighting was not like your fighting which is carried on for the sake of ruling."

We came to the Prophet and we were young men nearly of equal ages and we stayed with him for twenty nights. Allah's Apostle was a very kind man and when he realized our longing for our families, he asked us about those whom we had left behind. When we informed him, he said, "Go back to your families and stay with them and teach them (religion) and order them (to do good deeds). The Prophet mentioned things some of which I remembered and some I did not. Then he said, "Pray as you have seen me praying, and when it is the time of prayer, one of you should pronounce the call (Adhan) for the prayer and the eldest of you should lead the prayer. "

It has been narrated on the authority of 'Abdullah that, the Messenger of Allah (may peace be upon him) turned his face towards the Ka'ba and invoked God's imprecations upon six men of the Quraish, amorig whom were Abu Jahl. Umayya b. Khalaf, Utba b. Rabi'a, Shaiba b. Rabi'a and 'Uqba b. Abu Mu'ait I swear by God that I saw them lying slain in the battlefield of Badr. It being a hot day, their complexion had changed (showing signs of decay).

Once the Prophet went out during the day. Neither did he talk to me nor I to him till he reached the market of Bani Qainuqa and then he sat in the compound of Fatima's house and asked about the small boy (his grandson Al-Hasan) but Fatima kept the boy in for a while. I thought she was either changing his clothes or giving the boy a bath. After a while the boy came out running and the Prophet embraced and kissed him and then said, 'O Allah! Love him, and love whoever loves him.'

A man from the companions of the Prophet said, "Two men abused each other in front of the Prophet and one of them became angry and his anger became so intense that his face became swollen and changed. The Prophet said, "I know a word the saying of which will cause him to relax if he does say it." Then a man went to him and informed him of the statement of the Prophet and said, "Seek refuge with Allah from Satan." On that, angry man said, 'Do you find anything wrong with me? Am I insane? Go away!"

The Prophet divided and distributed something as he used to do for some of his distributions. A man from the Ansar said, "By Allah, in this division the pleasure of Allah has not been intended." I said, "I will definitely tell this to the Prophet ." So I went to him while he was sitting with his companions and told him of it secretly. That was hard upon the Prophet and the color of his face changed, and he became so angry that I wished I had not told him. The Prophet then said, "Moses was harmed with more than this, yet he remained patient."

From his father, from his grandfather, that the Messenger of Allah (saws) said: "Both the buyer and the seller retain the option as long as they did not separate, unless they agreed to making it optional. And it is not lawful for him to separate from his companion, fearing that he will change his mind."

[Abu 'Eisa said:] This Hadith is Hasan and this means separating from him after the sale, fearing that he will change his mind. And if the separation referred to speech, and there was no option left for him after the sale, then this Hadith would be meaningless, since he (saws) said: "And it is not lawful for him to separate from his companion, fearing that he will change his mind."
