1. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from ibn Ri’ab from Zurarah who has said the following: “I once asked abu Ja‘far عليه السلام, about a man who in the state of ‘Itikaf engages in sexual intercourse with his wife. He (the Imam) said, ‘If he does it he is required to do what one is required to do because of Zihar’ (calling on oath the back of one’s wife as the back of one’s mother) that is, two consecutive months of fasting.’”
