3. Ali has narrated from his father from ibn Mahbub from ibn Ri’ab from Zurarah who has said the following: “I once asked abu Ja’far , about al-Zihar. He (the Imam) said, ’It applies to all relatives (Dhi Mahram) like mother, sister, paternal or maternal aunts. Al-Zihar is not by swearing.’ I then asked, ’How does it take place?’ He (the Imam) said, ‘It happens by a man’s saying to his wife when she is clean of Hayd (menses) and sexual intercourse,

‘You are unlawful to me like the back of my mother or sister’, and he thereby intends al-Zihar.’”
