Musannaf Ibn Abi Shaybah 39694 — Reports on the conquest of Makkah

Al-Zuhri narrates that a man of Banu al-Dil bin Bakr said: "I would love to see the Messenger of Allah (peace and blessings be upon him) and hear some of his (peace and blessings be upon him) sayings." So he said to a man: "Go with me." The man said: "I fear that the people of Khuza'ah will kill me." He kept urging him until he set out. Then a man of the tribe of Khuza'ah met him, recognised him, and struck him in the stomach with a sword. The slain man said: "I told you (before) that they would kill me." When this reached the Prophet (peace and blessings be upon him), he (peace and blessings be upon him) stood up, praised and glorified Allah Almighty, and then said: "Indeed, Allah Almighty (Himself) made Makkah sacred; it was not people who made it sacred. It was made lawful for me only for a single hour of the day, and after that it is still sacred. And the people most hostile toward Allah Almighty are three: the man who kills in Makkah, the man who kills someone other than the killer, and the man who seeks the vengeance of the days of ignorance. So I (myself) will surely pay the blood money of this man."
