It is narrated from Urwah bin Zubair that there was a man from the Ansar whose name was Uhayhah bin Julah, and he had a younger paternal uncle who was staying with his maternal relatives. Uhayhah took him and killed him. The people of his maternal relatives said: We raised him, nurtured him, and when he grew up, his nephew overpowered us and took him away. Urwah said: For this reason (now in Islam) the killer does not inherit from the murdered person.
Imam Malik, may Allah have mercy on him, said: In our view, there is no difference of opinion in this that the one who commits intentional murder does not inherit the blood money (diyah) of the murdered person, nor his wealth, nor can he deprive any heir. And the one who commits accidental killing does not inherit the blood money, but whether he inherits the rest of the wealth or not, there is a difference of opinion in this. In my view, he will inherit the rest of the wealth.
