Musannaf Ibn Abi Shaybah 29743 — What makes a Muslim's blood lawful

Abu Husayn said: Sayyiduna Uthman (may Allah be pleased with him) looked down on the people on the Day of the House and said: Do you not know that the blood of a Muslim person is not lawful, except for four people: a man who has killed, so he will be killed in turn; or a man who commits adultery after being married; or a man who apostatizes after having embraced Islam; or a man who does the act of the people of Lut, that is, sodomy.
