It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever among the Muslims changes his religion (becomes an apostate), kill him. And when a servant says, 'I bear witness that there is no god but Allah and that Muhammad (peace and blessings be upon him) is His servant and Messenger,' then we have no way against him except by its right (that is, if he commits a crime, the prescribed punishment will be established upon him)." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man from the Ansar accepted Islam, then he apostatized and joined the polytheists. Then he felt remorse and sent a message to his people to ask the Messenger of Allah (peace and blessings be upon him): Is there any way of repentance for me? Then these verses were revealed, from "How shall Allah guide a people who disbelieved after their belief and had witnessed that the Messenger is true and clear proofs had come to them" to "except those who repent after that and make amends; for indeed Allah is Forgiving, Merciful" [Surah Al Imran: 86 - 89] . The narrator said: The people of his tribe came to him, and he accepted Islam again. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Furat bin Hayyan (may Allah be pleased with him). He (Furat bin Hayyan) was a spy for Abu Sufyan and an ally (of the polytheists), and the Messenger of Allah (peace and blessings be upon him) had ordered that he be killed. He passed by a gathering of the Ansar and said: I am a Muslim. The Messenger of Allah (peace and blessings be upon him) said: "Among you are men whom we entrust to their faith, and Furat bin Hayyan is one of them." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that (in Madinah) there were two tribes, Banu Qurayzah and Banu Nadir, and Banu Nadir had superiority over Banu Qurayzah. So when a man of Banu Qurayzah killed a man of Banu Nadir, he was killed in return for him, but when a man of Banu Nadir killed a man of Banu Qurayzah, instead of retaliation (qisas), his blood money was fixed at a hundred wasqs of dates. When the Prophet (peace and blessings be upon him) was sent, a man of Banu Nadir killed a man of Banu Qurayzah. They demanded: Hand him over to us so that we may kill him in retaliation. The others said: The Prophet (peace and blessings be upon him) will judge between us and you. They came to him (peace and blessings be upon him), and this verse was revealed: "And if you judge, judge between them with justice; indeed Allah loves those who act justly" [Surah al-Ma'idah: 42] . And justice (qist) is that a life be taken for a life. Then this verse was revealed: "Is it the judgment of (the time of) ignorance they seek?" [Surah al-Ma'idah: 50] This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
