الكبرى للنسائي:٨٩٥٤أَخْبَرَنَا الرَّبِيعُ بْنُ سُلَيْمَانَ بْنِ دَاوُدَ قَالَ حَدَّثَنَا عَبْدُ اللهِ بْنُ عَبْدِ الْحَكَمِ قَالَ أَخْبَرَنَا بَكْرُ بْنُ مُضَرَ عَنْ يَزِيدَ بْنِ عَبْدِ اللهِ عَنْ عُثْمَانَ بْنِ كَعْبٍ الْقُرَظِيِّ عَنْ مُحَمَّدِ بْنِ كَعْبٍ الْقُرَظِيِّ أَنَّ §رَجُلًا سَأَلَهُ عَنِ الْمَرْأَةِ تُؤْتَى فِي دُبُرِهَا فَقَالَ

مُحَمَّدٌ إِنَّ عَبْدَ اللهِ بْنَ عَبَّاسٍ كَانَ يَقُولُ «اسْقِ حَرْثَكَ مِنْ حَيْثُ نَبَاتِهِ»
