A man who enters under safe conduct and is killed

It is narrated from Ziyad bin Muslim that a man from the people of India came to Aden under a grant of security, and a Muslim man killed him in retaliation for his brother. A letter was written about this to Umar bin Abd al-Aziz, and he wrote back: "Do not kill him. Take the blood money (diyah) from him and send it to the heirs of the slain man." And he ordered that the killer be imprisoned.

It is narrated from al-Hasan (may Allah have mercy on him) that a man from the polytheists went on Hajj, and when he was returning, a Muslim man killed him. The Prophet (peace and blessings be upon him) ordered him (the killer) to pay the blood money to his family.

It is narrated from Yusuf bin Ya'qub that a polytheist killed a Muslim, and then he came under a grant of security, and the brother of the slain man killed him. Umar bin Abd al-Aziz gave a ruling of blood money against him, made it payable from his own wealth, had him imprisoned, and sent the blood money to the slain man's heirs in the abode of war.
