'Abdullah b. Mughaffal reported Allah's Messenger ﷺ as saying, “No one must pass water where he bathes and then wash in it or perform ablution in it, for all evil promptings come from it.” Abu Dawud transmitted it, as did Tirmidhi and Nasa’i, but they did not mention “then wash in it or perform ablution in it”.

Ibn ‘Umar reported the Prophet (ﷺ) as saying, ‘‘Jahannam has seven gates, one of which is for those who draw a sword against my people,” or he said, "against Muhammad’s people.” Tirmidhi transmitted it, saying this is a gharib tradition.

Rafi' b. Khadij and Sahl b. Abu Hathma told that ‘Abdallah b. Sahl and Muhayyisa b. Mas'ud came to Khaibar and when they had separated among the palm-trees ‘Abdallah b. Sahl was killed. ‘Abd ar-Rah¬man b. Sahl and Huwayyisa, and Muhayyisa, the sons of Mas'ud, came to the Prophet (ﷺ) and spoke about what had happened to their friend. ‘Abd ar-Rahman who was the youngest spoke first, but the Prophet (ﷺ) said to him kabbir al-kubr, which was said by Yahya b. Sa'id to mean “Let the oldest take charge of speaking." They then spoke and the Prophet (ﷺ) said, “Make your demand regarding your dead man (or he said, your friend) by the oaths of fifty of you." They replied, “ Messenger of Allah , it is a matter which we did not see." He said, “The Jews will exonerate themselves by the oaths of fifty of them," but they replied, “Messenger of Allah, they are a people who are infidels." So Allah's Messenger ﷺ paid them the blood wit himself. A version has, “You must swear fifty oaths and make your claim regarding your slain man (or, your friend)." Then Allah's Messenger ﷺ himself paid his blood wit consisting of a hundred she- camels. (Bukhari and Muslim.)

Rafi‘ b. Khadij said that one of the Ansar was killed at Khaibar and his relatives went to the Prophet (ﷺ) and mentioned that to him. He asked, “Have you two witnesses who can testify to the murderer of your friend?" They replied, “Messenger of Allah, there was not a single Muslim present, but only Jews who sometimes have the audacity to do even greater crimes than this “He said, “Then choose fifty of them and demand that they take an oath;" but they refused and Allah's Messenger ﷺ paid his blood wit himself. Abu Dawud transmitted it.

‘Ikrima told that when some heretics were brought to ‘Ali he had them burned, and that when Ibn ‘Abbas heard of it he said that if it had been he, he would not have had them burned because of Allah's Messenger ﷺ's prohibition, “Do not inflict Allah’s punishment on anyone”, but would have had them killed on account of the statement made by Allah's Messenger ﷺ, “Kill those who change their religion.” Bukhari transmitted it.

‘Abdallah b. ‘Abbas reported Allah's Messenger ﷺ as saying, “Only Allah punishes with fire.” Bukhari transmitted it.

‘Ali told that he heard Allah's Messenger ﷺ say, “In the last time people will come forth, young and foolish, speaking the finest words men speak, but their faith will not pass their throats. They will come out from the religion as an arrow does from the animal it is aimed at. Wherever you meet them kill them, for a reward for killing them will be given on the day of resurrection to those who kill them.” (Bukhari and Muslim.)

Abu Sa'id al-Khudri reported Allah's Messenger ﷺ 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 Allah's Messenger ﷺ 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 (ﷺ) 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 (ﷺ) 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.)
