Abu Huraira told that Sa'd b. ‘Ubada asked, “If I were to find a man with my wife, should I not touch him before bringing four witnesses?” Then when God’s Messenger replied that that was so, he said, “By no means. I swear by Him who has sent you with the truth that I would take my sword to him before that.” God’s Messenger said, “Listen to what your chief says. He is jealous of his honour, but I am more jealous than he is and God is more jealous than I am.” Muslim transmitted it.
