Musannaf Ibn Abi Shaybah 29718 — A man who finds a man with his wife

Sayyiduna al-Mughirah (may Allah be pleased with him) said: The news reached the Prophet (peace and blessings be upon him) that Sayyiduna Sa'd bin Ubadah (may Allah be pleased with him) was saying: If I find a man with my wife, I will strike him with the edge of the sword. Upon this the Prophet (peace and blessings be upon him) said: "Are you amazed at the jealousy of Sa'd? By Allah, I am more jealous than Sa'd, and Allah, the Lord of Honour, is more jealous than I am. And it is because of this that Allah has forbidden shameful deeds, whether they are open or hidden."
