الكبرى للنسائي:٩٦٥٥أَخْبَرَنِي عَبْدُ اللهِ بْنُ الْهَيْثَمِ بْنِ عُثْمَانَ الْبَصْرِيُّ قَالَ حَدَّثَنَا حَمَّادٌ وَهُوَ ابْنُ مَسْعَدَةَ عَنْ حَنْظَلَةَ هُوَ ابْنُ أَبِي سُفْيَانَ قَالَ سَمِعْتُ نَافِعًا يَقُولُ حَدَّثَتْنَا أُمُّ سَلَمَةَ أَنَّهَا لَمَّا ذُكِرَ فِي النِّسَاءِ مَا ذُكِرَ قَالَتْ

يَا رَسُولَ اللهِ أَرَأَيْتَ النِّسَاءَ؟ قَالَ «شِبْرًا» قَالَتْ لَا يَكْفِيهُنَّ قَالَ «فَذِرَاعٌ»
