Sulayman bin Yasar (may Allah have mercy on him) narrates from Sayyiduna Salamah bin Sakhr al-Bayadi (may Allah be pleased with him) that he said: I used to have intercourse with women so much that no one besides me even had such desire. When Ramadan began, I made zihar from my wife out of fear of falling into (intercourse with) her. I kept trying, but I did not have the strength to stay apart until morning. One night she was sitting near me when suddenly some part of her body was uncovered, and I ended up having intercourse with her. In the morning I told my people and said: "Come with me to the Messenger of Allah (peace and blessings be upon him)." They said: By Allah! We will not go with you; we fear that the Qur'an may be revealed about us, or that the Messenger of Allah (peace and blessings be upon him) may say something that becomes a cause of shame for us. Go yourself and do what you have to do. I came and informed the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Are you the one?" I said: Yes; carry out the punishment on me, for I am patient. He (peace and blessings be upon him) said: "Free a neck (slave)." I struck my own neck with my hand and said: I do not own anything besides this. He (peace and blessings be upon him) said: "Fast two consecutive months." He says: I said: O Messenger of Allah (peace and blessings be upon him)! All this happened only because of fasting. He (peace and blessings be upon him) said: "Feed sixty poor people." I said: O Messenger of Allah (peace and blessings be upon him)! We spent the night on empty stomachs; we did not even have an evening meal. He (peace and blessings be upon him) said: "Go to the one who collects the charity of Banu Zurayq; he will give you something. Feed one wasq to sixty poor people and give the rest to your family." I came to my people and said: I found hardship with you.
