The Prophet said, "Beware of suspicion (about others), as suspicion is the falsest talk, and do not spy upon each other, and do not listen to the evil talk of the people about others' affairs, and do not have enmity with one another, but be brothers. And none should ask for the hand of a girl who is already engaged to his (Muslim) brother, but one should wait till the first suitor marries her or leaves her."

When it was the day of Uhud, the pagans were defeated. Then Satan, Allah's Curse be upon him, cried loudly, "O Allah's Worshippers, beware of what is behind!" On that, the front files of the (Muslim) forces turned their backs and started fighting with the back files. Hudhaifa looked, and on seeing his father Al-Yaman, he shouted, "O Allah's Worshippers, my father, my father!" But by Allah, they did not stop till they killed him. Hudhaifa said, "May Allah forgive you." (The sub-narrator, `Urwa, said, "By Allah, Hudhaifa continued asking Allah's Forgiveness for the killers of his father till he departed to Allah (i.e. died).")

On the day (of the battle) of Uhud when the pagans were defeated, Satan shouted, "O slaves of Allah! Beware of the forces at your back," and on that the Muslims of the front files fought with the Muslims of the back files (thinking they were pagans). Hudhaifa looked back to see his father "Al-Yaman," (being attacked by the Muslims). He shouted, "O Allah's Slaves! My father! My father!" By Allah, they did not stop till they killed him. Hudhaifa said, "May Allah forgive you." `Urwa said that Hudhaifa continued to do good (invoking Allah to forgive the killer of his father till he met Allah (i.e. died).

Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "Beware of wisal. Beware of wisal." They said, "But you practise wisal, Messenger of Allah." He replied, "I am not the same as you. My Lord feeds me and gives me to drink."

I and Ashtar went to Ali and said to him: Did the Messenger of Allah (saws) give you any instruction about anything for which he did not give any instruction to the people in general?

He said: No, except what is contained in this document of mine. Musaddad said: He then took out a document. Ahmad said: A document from the sheath of his sword.

It contained: The lives of all Muslims are equal; they are one hand against others; the lowliest of them can guarantee their protection. Beware, a Muslim must not be killed for an infidel, nor must one who has been given a covenant be killed while his covenant holds. If anyone introduces an innovation, he will be responsible for it. If anyone introduces an innovation or gives shelter to a man who introduces an innovation (in religion), he is cursed by Allah, by His angels, and by all the people.

Musaddad said: Ibn AbuUrubah's version has: He took out a document.

We alighted with the Prophet (saws) at Khaybar, and he had his companions with him. The chief of Khaybar was a defiant and abominable man.

He came to the Prophet (saws) and said: Is it proper for you, Muhammad, that you slaughter our donkeys, eat our fruit, and beat our women?

The Prophet (saws) became angry and said: Ibn Awf, ride your horse, and call loudly: Beware, Paradise is lawful only for a believer, and that they (the people) should gather for prayer.

They gathered and the Prophet (saws) led them in prayer, stood up and said: Does any of you, while reclining on his couch, imagine that Allah has prohibited only that which is to be found in this Qur'an? By Allah, I have preached, commanded and prohibited various matters as numerous as that which is found in the Qur'an, or more numerous. Allah has not permitted you to enter the houses of the people of the Book without permission, or beat their women, or eat their fruits when they give you that which is imposed on them.

Allah's Apostle recited the Verse:-- "It is He who has sent down to you the Book. In it are Verses that are entirely clear, they are the foundation of the Book, others not entirely clear. So as for those in whose hearts there is a deviation (from the Truth ). follow thereof that is not entirely clear seeking affliction and searching for its hidden meanings; but no one knows its hidden meanings but Allah. And those who are firmly grounded in knowledge say: "We believe in it (i.e. in the Qur'an) the whole of it (i.e. its clear and unclear Verses) are from our Lord. And none receive admonition except men of understanding." (3.7) Then Allah's Apostle said, "If you see those who follow thereof that is not entirely clear, then they are those whom Allah has named [as having deviation (from the Truth)] 'So beware of them."

The Prophet said, "Beware! Do not renegade as (disbelievers) after me by striking (cutting) the necks of one another."

The Prophet (saws) said: Musaddad's version has: He addressed on the day of Conquest. The agreed version then goes: Beware! Every object of pride of pre-Islamic times, whether it is blood-vengeance or property, mentioned or claimed, has been put under my feet except supply of water to the pilgrims and custody of the House (the Ka'bah). He then said: Beware! The blood-wit for unintentional murder, such as is done with a whip and stick, is one hundred camels, forty of which are pregnant.

Once Bilal brought Barni (i.e. a kind of dates) to the Prophet and the Prophet asked him, "From where have you brought these?" Bilal replied, "I had some inferior type of dates and exchanged two Sas of it for one Sa of Barni dates in order to give it to the Prophet; to eat." Thereupon the Prophet said, "Beware! Beware! This is definitely Riba (usury)! This is definitely Riba (Usury)! Don't do so, but if you want to buy (a superior kind of dates) sell the inferior dates for money and then buy the superior kind of dates with that money."

'Uyaina bin Hisn bin Hudhaifa came and stayed with his nephew Al-Hurr bin Qais who was one of those whom `Umar used to keep near him, as the Qurra' (learned men knowing Qur'an by heart) were the people of `Umar's meetings and his advisors whether they were old or young. 'Uyaina said to his nephew, "O son of my brother! You have an approach to this chief, so get for me the permission to see him." Al-Hurr said, "I will get the permission for you to see him." So Al-Hurr asked the permission for 'Uyaina and `Umar admitted him. When 'Uyaina entered upon him, he said, "Beware! O the son of Al-Khattab! By Allah, you neither give us sufficient provision nor judge among us with justice." Thereupon `Umar became so furious that he intended to harm him, but Al-Hurr said, "O chief of the Believers! Allah said to His Prophet: "Hold to forgiveness; command what is right; and leave (don't punish) the foolish." (7.199) and this (i.e. 'Uyaina) is one of the foolish." By Allah, `Umar did not overlook that Verse when Al-Hurr recited it before him; he observed (the orders of) Allah's Book strictly.

The Prophet (saws) said: Beware! I have been given the Qur'an and something like it, yet the time is coming when a man replete on his couch will say: Keep to the Qur'an; what you find in it to be permissible treat as permissible, and what you find in it to be prohibited treat as prohibited. Beware! The domestic ass, beasts of prey with fangs, a find belonging to confederate, unless its owner does not want it, are not permissible to you If anyone comes to some people, they must entertain him, but if they do not, he has a right to mulct them to an amount equivalent to his entertainment.

When the prohibition of wine (was yet to be) declared, Umar said: O Allah, give us a satisfactory explanation about wine.

So the following verse of Surat al-Baqarah revealed; "They ask thee concerning wine and gambling. Say: In them is great sin...." Umar was then called and it was recited to him.

He said: O Allah, give us a satisfactory explanation about wine.

Then the following verse of Surat an-Nisa' was revealed: "O ye who believe! approach not prayers with a mind befogged...." Thereafter the herald of the Messenger of Allah (saws) would call when the (congregational) prayer was performed: Beware, one who is drunk should not come to prayer. Umar was again called and it was recited to him).

He said: O Allah, give us a satisfactory explanation about wine. This verse was revealed: "Will ye not then abstain?" Umar said: We abstained.

When the pagans were defeated during the (first stage) of the battle of Uhud, Satan shouted, "O Allah's slaves! Beware of what is behind you!" So the front files of the Muslims attacked their own back files. Hudhaifa bin Al-Yaman looked and on seeing his father he shouted: "My father! My father!" By Allah! The people did not stop till they killed his father. Hudhaifa then said, "May Allah forgive you." `Urwa (the sub-narrator) added, "Hudhaifa continued asking Allah forgiveness for the killers of his father till he met Allah (till he died).

In the year of the Conquest of Mecca, the tribe of Khuza`a killed a man from the tribe of Bam Laith in revenge for a killed person belonging to them in the Pre-lslamic Period of Ignorance. So Allah's Apostle got up saying, "Allah held back the (army having) elephants from Mecca, but He let His Apostle and the believers overpower the infidels (of Mecca). Beware! (Mecca is a sanctuary)! Verily! Fighting in Mecca was not permitted for anybody before me, nor will it be permitted for anybody after me; It was permitted for me only for a while (an hour or so) of that day. No doubt! It is at this moment a sanctuary; its thorny shrubs should not be uprooted; its trees should not be cut down; and its Luqata (fallen things) should not be picked up except by the one who would look for its owner. And if somebody is killed, his closest relative has the right to choose one of two things, i.e., either the Blood money or retaliation by having the killer killed." Then a man from Yemen, called Abu Shah, stood up and said, "Write that) for me, O Allah's Apostle!" Allah's Apostle said (to his companions), "Write that for Abu Shah." Then another man from Quraish got up, saying, "O Allah's Apostle! Except Al- Idhkhir (a special kind of grass) as we use it in our houses and for graves." Allah's Apostle said, "Except Al-idhkkir."

Ibn Yahya and `Amr added in their version : “ There will appear among my community people who will be dominated by desires like rabies which penetrates its patient”, `Amr’s version has: “penetrates its patient. There remains no vein and no joint but it penetrates it.”

The Messenger of Allah (saws) said: Beware of the wages of a distributor of booty (qusamah). We asked: What is qusamah (wages of a distributor)? He said: It means a thing which is shared by the people, and then it is reduced.

The Prophet said to me during Hajjat-al-Wada`, "Let the people keep quiet and listen." Then he said (addressing the people), "Beware! Do not renegade as disbelievers after me by striking (cutting) the necks of one another."

In the year of the Conquest of Mecca, the tribe of Khuza`a killed a man from the tribe of Bani Laith in revenge for a killed person, belonging to them. They informed the Prophet about it. So he rode his Rahila (she-camel for riding) and addressed the people saying, "Allah held back the killing from Mecca. (The sub-narrator is in doubt whether the Prophet said "elephant or killing," as the Arabic words standing for these words have great similarity in shape), but He (Allah) let His Apostle and the believers over power the infidels of Mecca. Beware! (Mecca is a sanctuary) Verily! Fighting in Mecca was not permitted for anyone before me nor will it be permitted for anyone after me. It (war) in it was made legal for me for few hours or so on that day. No doubt it is at this moment a sanctuary, it is not allowed to uproot its thorny shrubs or to uproot its trees or to pick up its Luqat (fallen things) except by a person who will look for its owner (announce it publicly). And if somebody is killed, then his closest relative has the right to choose one of the two-- the blood money (Diyya) or retaliation having the killer killed. In the meantime a man from Yemen came and said, "O Allah's Apostle! Get that written for me." The Prophet ordered his companions to write that for him. Then a man from Quraish said, "Except Al-Idhkhir (a type of grass that has good smell) O Allah's Apostle, as we use it in our houses and graves." The Prophet said, "Except Al-Idhkhir i.e. Al-Idhkhir is allowed to be plucked."

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.

Yahya related to me from Malik that he had heard that Isa ibn Maryam used to say, "O Banu Israil! You must drink pure water and the green things of the land and barley bread . Beware of wheat bread, for you will not be grateful enough for it."

Allah's Apostle said, "Beware of entering upon the ladies." A man from the Ansar said, "Allah's Apostle! What about Al-Hamu the in-laws of the wife (the brothers of her husband or his nephews etc.)?" The Prophet replied: The in-laws of the wife are death itself.

Allah's Apostle said, 'Beware of suspicion, for it is the worst of false tales and don't look for the other's faults and don't spy and don't hate each other, and don't desert (cut your relations with) one another O Allah's slaves, be brothers!" (See Hadith No. 90)

Yahya related to me from Malik that Yahya ibn Said said that he heard Said ibn al-Musayyab say, "Shall I tell you what is better than much prayer and sadaqa?" They said, "Yes." He said, "Mending discord. And beware of hatred - it strips you (of your deen)."
