حَدَّثَنَا الْعَبَّاسُ بْنُ يَزِيدَ، قَالَ حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا مَعْمَرٌ، عَنِ الْحَكَمِ بْنِ أَبَانَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَجُلاً، ظَاهَرَ مِنِ امْرَأَتِهِ فَغَشِيَهَا قَبْلَ أَنْ يُكَفِّرَ فَأَتَى النَّبِيَّ ـ صلى الله عليه وسلم ـ فَذَكَرَ ذَلِكَ لَهُ فَقَالَ ‏"‏ مَا حَمَلَكَ عَلَى ذَلِكَ ‏"‏ ‏.‏ فَقَالَ يَا رَسُولَ اللَّهِ رَأَيْتُ بَيَاضَ حِجْلَيْهَا فِي الْقَمَرِ فَلَمْ أَمْلِكْ نَفْسِي أَنْ وَقَعْتُ عَلَيْهَا ‏.‏ فَضَحِكَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَأَمَرَهُ أَلاَّ يَقْرَبَهَا حَتَّى يُكَفِّرَ ‏.‏

It was narrated from Ibn 'Abbas that: a man declared Zihar upon his wife, then he had intercourse with her before offering expiation. He came to the Prophet (PBUH) and told him about that. He said: "What made you do that?" He said: "I saw her ankles in the moonlight, and I could not control myself, and I had intercourse with her." The Messenger of Allah (PBUH) smiled and told him not to go near her until he had offered expiation. Translation Not Available
