Musannaf Ibn Abi Shayba 18:782

Abu Bakr narrated to us, he said: Abd al-A’la narrated to us, from Muhammad ibn Ishaq, from al-Zuhri, from Sa’id ibn al-Musayyib and from Makhul, from Umar ibn Abd al-Aziz, that they both said: The man is compensated for the woman in one-third of her blood money, then they differ.
