The prostration of Sa`d is not a compulsory one but I saw the Prophet prostrating while reciting it.

AbdurRahman ibn Ka'b ibn Malik said: When Ka'b ibn Malik heard the call to prayer on Friday, he prayed for As'ad ibn Zurarah. I asked him: What is the matter that when you hear the call to prayer, you pray for As'ad ibn Zurarah? He replied: This is because he held the Friday prayer for the first time for us at Hazm an-Nabit of Harrah belonging to Banu Bayadah in Naqi', called Naqi' al-Khadumat. I asked him: How many were you at that time ? He said: Forty.

Yahya related to me from Malik from Yazid ibn Abdullah ibn Qusayt from Muhammad ibn Abd ar-Rahman ibn Thawban from his mother that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said that the Messenger of Allah, may Allah bless him and grant him peace, ordered that the skins of carrion be used after they had been tanned.

This very hadith has been narrated on the authority of Sbu'ba with the same chain of transmitters.

I heard Allah's Apostle saying, "The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended. So whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for."

(the mother of the faithful believers) Al-Harith bin Hisham asked Allah's Apostle "O Allah's Apostle! How is the Divine Inspiration revealed to you?" Allah's Apostle replied, "Sometimes it is (revealed) like the ringing of a bell, this form of Inspiration is the hardest of all and then this state passes off after I have grasped what is inspired. Sometimes the Angel comes in the form of a man and talks to me and I grasp whatever he says." 'Aisha added: Verily I saw the Prophet being inspired divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over).

Ibn 'Abbas in the explanation of the statement of Allah "Move not your tongue concerning (the Quran) to make haste therewith." (75.16) said "Allah's Apostle used to bear the revelation with great trouble and used to move his lips (quickly) with the Inspiration." Ibn 'Abbas moved his lips saying, "I am moving my lips in front of you as Allah's Apostle used to move his." Said moved his lips saying: "I am moving my lips, as I saw Ibn 'Abbas moving his." Ibn 'Abbas added, "So Allah revealed 'Move not your tongue concerning (the Qur'an) to make haste therewith. It is for Us to collect it and to give you (O Muhammad) the ability to recite it (the Quran)' (75.16-17) which means that Allah will make him (the Prophet) remember the portion of the Qur'an which was revealed at that time by heart and recite it. The statement of Allah: 'And when we have recited it to you (O Muhammad through Gabriel) then you follow its (Quran) recital' (75.18) means 'listen to it and be silent.' Then it is for Us (Allah) to make it clear to you' (75.19) means 'Then it is (for Allah) to make you recite it (and its meaning will be clear by itself through your tongue). Afterwards, Allah's Apostle used to listen to Gabriel whenever he came and after his departure he used to recite it as Gabriel had recited it."

Allah's Apostle was the most generous of all the people, and he used to reach the peak in generosity in the month of Ramadan when Gabriel met him. Gabriel used to meet him every night of Ramadan to teach him the Qur'an. Allah's Apostle was the most generous person, even more generous than the strong uncontrollable wind (in readiness and haste to do charitable deeds).

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.

Allah's Apostle said: Islam is based on (the following) five (principles):

1. To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Apostle.

2. To offer the (compulsory congregational) prayers dutifully and perfectly.

3. To pay Zakat (i.e. obligatory charity) .

4. To perform Hajj. (i.e. Pilgrimage to Mecca)

5. To observe fast during the month of Ramadan.

The Prophet said, "Faith (Belief) consists of more than sixty branches (i.e. parts). And Haya (This term "Haya" covers a large number of concepts which are to be taken together; amongst them are self respect, modesty, bashfulness, and scruple, etc.) is a part of faith."

The Prophet said, "A Muslim is the one who avoids harming Muslims with his tongue and hands. And a Muhajir (emigrant) is the one who gives up (abandons) all what Allah has forbidden."

Some people asked Allah's Apostle, "Whose Islam is the best? i.e. (Who is a very good Muslim)?" He replied, "One who avoids harming the Muslims with his tongue and hands."

A man asked the Prophet , "What sort of deeds or (what qualities of) Islam are good?" The Prophet replied, 'To feed (the poor) and greet those whom you know and those whom you do not Know (See Hadith No. 27).

The Prophet said, "None of you will have faith till he wishes for his (Muslim) brother what he likes for himself."

"Allah's Apostle said, "By Him in Whose Hands my life is, none of you will have faith till he loves me more than his father and his children."

The Prophet said "None of you will have faith till he loves me more than his father, his children and all mankind."

The Prophet said, "Whoever possesses the following three qualities will have the sweetness (delight) of faith:

1. The one to whom Allah and His Apostle becomes dearer than anything else.

2. Who loves a person and he loves him only for Allah's sake.

3. Who hates to revert to Atheism (disbelief) as he hates to be thrown into the fire."

The Prophet said, "Love for the Ansar is a sign of faith and hatred for the Ansar is a sign of hypocrisy."

who took part in the battle of Badr and was a Naqib (a person heading a group of six persons), on the night of Al-'Aqaba pledge: Allah's Apostle said while a group of his companions were around him, "Swear allegiance to me for:

1. Not to join anything in worship along with Allah.

2. Not to steal.

3. Not to commit illegal sexual intercourse.

4. Not to kill your children.

5. Not to accuse an innocent person (to spread such an accusation among people).

6. Not to be disobedient (when ordered) to do good deed."

The Prophet added: "Whoever among you fulfills his pledge will be rewarded by Allah. And whoever indulges in any one of them (except the ascription of partners to Allah) and gets the punishment in this world, that punishment will be an expiation for that sin. And if one indulges in any of them, and Allah conceals his sin, it is up to Him to forgive or punish him (in the Hereafter)." 'Ubada bin As-Samit added: "So we swore allegiance for these." (points to Allah's Apostle)

Allah's Apostle said, "A time will soon come when the best property of a Muslim will be sheep which he will take on the top of mountains and the places of rainfall (valleys) so as to flee with his religion from afflictions."

Whenever Allah's Apostle ordered the Muslims to do something, he used to order them deeds which were easy for them to do, (according to their strength and endurance). They said, "O Allah's Apostle! We are not like you. Allah has forgiven your past and future sins." So Allah's Apostle became angry and it was apparent on his face. He said, "I am the most Allah fearing, and know Allah better than all of you do."

The Prophet said, "Whoever possesses the following three qualities will taste the sweetness of faith:

1. The one to whom Allah and His Apostle become dearer than anything else.

2. Who loves a person and he loves him only for Allah's sake.

3. Who hates to revert to disbelief (Atheism) after Allah has brought (saved) him out from it, as he hates to be thrown in fire."

The Prophet said, "When the people of Paradise will enter Paradise and the people of Hell will go to Hell, Allah will order those who have had faith equal to the weight of a grain of mustard seed to be taken out from Hell. So they will be taken out but (by then) they will be blackened (charred). Then they will be put in the river of Haya' (rain) or Hayat (life) (the Narrator is in doubt as to which is the right term), and they will revive like a grain that grows near the bank of a flood channel. Don't you see that it comes out yellow and twisted"

Allah's Apostle said, "While I was sleeping I saw (in a dream) some people wearing shirts of which some were reaching up to the breasts only while others were even shorter than that. Umar bin Al-Khattab was shown wearing a shirt that he was dragging." The people asked, "How did you interpret it? (What is its interpretation) O Allah's Apostle?" He (the Prophet ) replied, "It is the Religion."

Once Allah's Apostle passed by an Ansari (man) who was admonishing his brother regarding Haya'. On that Allah's Apostle said, "Leave him as Haya' is a part of faith." (See Hadith 9)

Allah's Apostle said: "I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Apostle, and offer the prayers perfectly and give the obligatory charity, so if they perform that, then they save their lives and property from me except for Islamic laws and then their reckoning (accounts) will be done by Allah."

Allah's Apostle was asked, "What is the best deed?" He replied, "To believe in Allah and His Apostle (Muhammad). The questioner then asked, "What is the next (in goodness)? He replied, "To participate in Jihad (religious fighting) in Allah's Cause." The questioner again asked, "What is the next (in goodness)?" He replied, "To perform Hajj (Pilgrim age to Mecca) 'Mubrur, (which is accepted by Allah and is performed with the intention of seeking Allah's pleasure only and not to show off and without committing a sin and in accordance with the traditions of the Prophet)."
