Musannaf Ibn Abi Shaybah 29638 — Reports on the qasamah

Ma'mar said: Imam al-Zuhri was asked about a slain man who was found in a man's house. The owner of the house said: He came to me at night to steal my property, so I killed him. The family of the slain man said: This man himself called him to his house and killed him. Al-Zuhri said: If fifty of the slain man's family swear that the owner of the house called him and killed him, I shall take retaliation from him. If they refuse to swear, these people shall be liable for the blood money.
