Musannaf Ibn Abi Shaybah 29711 — A man who finds a man with his wife

Abu Asim said that al-Sha'bi said: Two men of the Ansar were brothers, one of whom was named Ash'ath. He went out to fight in one of the armies of the Muslims. Then his brother's wife said to his brother: There is a man with your brother's wife; can you do anything about it? So the man who had stayed behind climbed onto the roof and looked into his brother's house, and he saw a man with his brother's wife on the bed, while the woman was plucking a chicken for him, and the man was reciting these verses: "Islam has deceived Ash'ath about me. I passed the night with his bride. I spend the night clinging to his wife, while he spends the evening on a dark, lean-bellied mare. The flesh of her body is like the cushions of a litter laid one on top of another."
