Abu Sa'id al-Khudri reported God’s Messenger as saying,“My people will be in two sections from among whom a seceding party will go out, and those who are nearest to the truth will undertake the killing of them.”Muslim transmitted it.

Jarir reported God’s Messenger as saying at the Farewell Pilgrimage,“You must never revert to infidelity after my death and cut off one another’s heads.”(Bukhari and Muslim.)

Abu Bakra reported the Prophet as saying,“When two Muslims meet and one of them bears arms against his brother, they are both on the brink of hell, and if one of them kills the other they will both enter it.”In a version on Abu Bakra's authority he said,“When two Muslims meet with their swords, the one who kills and the one who is killed will go to hell." When he (i.e. Abu Bakr) remarked that one was the killer and asked what was wrong with the one who was killed, he replied,“He was eager to kill his companion." (Bukhari and Muslim.)

Anas told that some people of ‘Ukl who had come to the Prophet and accepted Islam found Medina unhealthy, so he ordered them to go to the camels of the sadaqa and drink some of their urine and their milk. They did so and became well, after which they apostatised, killed the herdsmen and drove off the camels. So he sent people in pursuit of them, and when they were brought he had their hands and feet cut off and their eyes put out and left them to die without cauterising them to stop the flow of blood. A version says nails were driven into their eyes. Another says he ordered nails to be heated and after having them blinded with them he had them thrown out on the harra, and although they begged for water they were left to die without being given any. (Bukhari and Muslim.)

‘Imran b. Husain said God's Messenger used to urge them to give sadaqa and forbid them to mutilate anyone. Aba Dawud transmitted it.

‘Abd ar-Rahman b. Abdallah quoted his father as saying:When I we were on a journey with God’s Messenger and he had gone to relieve himself we saw a hummara* with two young ones and took the young ones, whereupon the hummara came and began to spread out its wings. Then when the Prophet came he said,“Who has pained this one by the loss of her young? Give her young ones back to her." He also saw an anthill which we had burned, and when he asked who had burned it and we replied that we had, he said,“It is not fitting that anyone but the Lord of the fire should punish with fire”Abu Dawud transmitted it. * A small bird like a sparrow, or a lark.

Abu Sa'id al-Khudri and Anas b Malik reported God’s Messenger as saying,“Disagreement and division will arise among my people. Some will speak well but do evil; they will recite the Qur’an but it will go no farther than their throats; they will swerve from the religion as an arrow goes through the animal shot at and will not return till an arrow comes back to the place where it was strung. They are the worst of men and animals. Blessed are they who kill them and are killed by them! They summon people to God’s Book, but they have no part with us. He who fights with them is nearer to God than they.”God’s Messenger was asked what mark they had, and said it was shaving.* Abu Dawud transmitted it. * Tahliq is here explained as going to extremes in shaving the head and taking the hair out by the roots.

A’isha reported God’s Messenger as saying,“The blood of a Muslim man who testifies that there is no god but God and that Muhammad is God’s Messenger may lawfully be shed only for one of three reasons:fornication after marriage, in which case he should be stoned; one who goes forth to fight with God and His Messenger,* in which case he should be killed, or crucified, or made a fugitive; or one which commits murder for which he is killed.”Abu Dawud transmitted it. * Mirqat iv. 53 refers this to such things as highway robbery.

Ibn Abu Laila said he was told by Muhammad’s companions that during a journey with God’s Messenger while one of them was asleep another went to a rope he had with him and seized him,* with the result that he was startled. God’s Messenger then said,“It is not lawful for a Muslim to frighten another.”Abu Dawud transmitted it. * The meaning is that he tied the rope round him while he was asleep, presumably as a joke.
