Musannaf Ibn Abi Shaybah 29463 — A man who strikes another man until

Yahya bin Sa'id said: In the time of Umar bin Abd al-Aziz, two bedouin men had a dispute in Madinah. One of them said to his companion: "By Allah, I struck him until he lost control of his bowels." He said: "Bear witness, for by Allah he has spoken the truth." Then Umar bin Abd al-Aziz sent a messenger to Sa'id bin al-Musayyib, asking: If a man struck someone until he lost control of his bowels, has any ruling been passed on it, or is there any established Sunnah? Sa'id said: In such a case Sayyiduna Uthman (may Allah be pleased with him) ruled a third of the blood money.
