Ziyad bin Khaythama al-Ja'fi زياد بن خيثمة الجعفي · The Chapters on Blood Money

“I am the heir of the one who has no heir, and I will pay blood money on his behalf and inherit from him, and the maternal uncle is the heir of the one who has no heir; he pays the blood money on his behalf and inherits from him.'”

“Whoever kills out of folly or for tribal motives, using a rock, a whip, or a stick; he must pay the blood money for killing by mistake. Whoever kills deliberately, he is to be killed in retaliation. Whoever tries to prevent that, upon him is the curse of Allah, the angels and all the people, and no change nor equitable exchange will be accepted from him.”
