'Ikrimah said:

"A man came to the Prophet of Allah and said: 'O Prophet of Allah,' and that he had declared Zihar to his wife, then he had intercourse with her before he did what he had to do. He said: 'What made you do that?' He said: 'O Prophet of Allah! I saw the whiteness of her calves in the moonlight.' The Prophet ﷺ said: 'Keep away until you have done what you have to do.' (One of the narrators) Ishaq said in his Hadith: "Keep away from her until you have done what you have to do." The wording is that of Muhammad.

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا الْمُعْتَمِرُ، ح وَأَنْبَأَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ الْحَكَمَ بْنَ أَبَانَ، قَالَ سَمِعْتُ عِكْرِمَةَ، قَالَ أَتَى رَجُلٌ نَبِيَّ اللَّهِ ﷺ فَقَالَ يَا نَبِيَّ اللَّهِ إِنَّهُ ظَاهَرَ مِنِ امْرَأَتِهِ ثُمَّ غَشِيَهَا قَبْلَ أَنْ يَفْعَلَ مَا عَلَيْهِ . قَالَ " مَا حَمَلَكَ عَلَى ذَلِكَ " . قَالَ يَا نَبِيَّ اللَّهِ رَأَيْتُ بَيَاضَ سَاقَيْهَا فِي الْقَمَرِ . قَالَ نَبِيُّ اللَّهِ ﷺ " فَاعْتَزِلْ حَتَّى تَقْضِيَ مَا عَلَيْكَ " . وَقَالَ إِسْحَاقُ فِي حَدِيثِهِ " فَاعْتَزِلْهَا حَتَّى تَقْضِيَ مَا عَلَيْكَ " . وَاللَّفْظُ لِمُحَمَّدٍ . قَالَ أَبُو عَبْدِ الرَّحْمَنِ الْمُرْسَلُ أَوْلَى بِالصَّوَابِ مِنَ الْمُسْنَدِ وَاللَّهُ سُبْحَانَهُ وَتَعَالَى أَعْلَمُ .
