Musannaf Ibn Abi Shaybah

Hazrat Yahya bin Saeed narrates that during the time of Hazrat Umar bin Abdul Aziz, two villagers had a dispute in Madinah. One of them said to his companion: "By Allah, I beat him until his excrement came out." The other said, "Bear witness that by Allah, he has spoken the truth." Then Hazrat Umar bin Abdul Aziz sent a messenger to Hazrat Saeed bin Musayyib and asked: "If a man beats someone until his excrement comes out, is there any ruling or Sunnah regarding this?" Hazrat Saeed replied: "In this case, Hazrat Uthman decided on one-third of the blood money (diyat)."
