Hadith 16334828 - وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ قَالَ: سَأَلْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلظِّهَارِ فَقَالَ "هُوَ مِنْ كُلِّ ذِي مَحْرَمٍ أَوْ مِنْ أُمٍّ أَوْ أُخْتٍ أَوْ عَمَّةٍ أَوْ خَالَةٍ وَ لاَ يَكُونُ اَلظِّهَارُ فِي يَمِينٍ " فَقُلْتُ وَ كَيْفَ يَكُونُ قَالَ "يَقُولُ اَلرَّجُلُ لاِمْرَأَتِهِ وَ هِيَ طَاهِرٌ مِنْ غَيْرِ جِمَاعٍ أَنْتِ عَلَيَّ حَرَامٌ مِثْلَ ظَهْرِ أُمِّي أَوْ أُخْتِي وَ هُوَ يُرِيدُ بِذَلِكَ اَلظِّهَارَ ".
Hadith.4828 - Al-Hasan ibn Mahbub narrated from Ali ibn Ri'ab, from Zurara, who said:
I asked Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (as) about ẓihar (a form of divorce by comparison).
Imam (as) said: "Ẓihar applies only when a man likens his wife to someone who is permanently unlawful for him, such as his mother, sister, paternal aunt, or maternal aunt. Ẓihar does not occur through an oath."
I asked: "How does it occur?"
Imam (as) replied: "A man says to his wife, while she is in a state of purity and without having had intercourse with her, 'You are to me as unlawful as the back of my mother or my sister,' and he intends by this statement to make ẓihar."
