Musannaf Ibn Abi Shaybah 29510 — A man killed by a group

Abu Ishaq said that Sa'id bin Wahb said: Some men set out on a journey and another man accompanied them. When they returned, that man was not with them. The narrator said: That man's family accused those travellers. At this Shurayh said: Bring your witnesses that they killed your companion; otherwise these people will swear by Allah that they did not kill him. So the people brought them to Sayyiduna Ali (may Allah be pleased with him), and I was with him. He separated them from one another, and they confessed. The narrator said: I heard Sayyiduna Ali (may Allah be pleased with him) saying: I am Abu al-Hasan, the experienced one. Then, on his order, they were killed.
