Hazrat Zuhri narrates that a man from Banu Duhl bin Bakr said: I wish to visit the Messenger of Allah, peace and blessings be upon him, and to hear some instructions from him. So he said to another man: Come with me. That man said: I fear that the people of Banu Khuza’ah might kill me. (Nevertheless) he kept walking with him until a man from the tribe of Khuza’ah met him and recognized him, and struck him in the stomach with a sword. The slain man said: I had already informed you that these people would kill me. Then this matter reached the Noble Prophet, peace and blessings be upon him, so he stood up, praised and glorified Allah, and then said:“Indeed, Allah Himself has made Makkah a sanctuary; people did not make Makkah a sanctuary. This Makkah was made lawful for me for a moment of the day, and after that it is still forbidden. And the three people who are the greatest enemies of Allah Almighty are: the man who kills in Makkah, the man who kills someone who did not kill, and the man who seeks revenge from the days of ignorance. Therefore, I myself will pay the blood money for this man.”
