Musannaf Ibn Abi Shayba 18:1341

Abu Bakr narrated to us, he said: Ibn Mahdi narrated to us, from al-Qasim ibn al-Fadl, from Harun, from Ikrimah, regarding a man who was killed after the blood money (diyah) had been taken. He said: He is to be killed. Have you not heard Allah saying: "For them is a painful punishment"?
