الكبرى للنسائي:٨٣١٤ – أَخْبَرَنَا عُبَيْدُ اللهِ بْنُ سَعْدِ بْنِ إِبْرَاهِيمَ بْنِ سَعْدٍ قَالَ حَدَّثَنَا عَمِّي قَالَ حَدَّثَنَا أَبِي عَنِ الْوَلِيدِ بْنِ كَثِيرٍ عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ حَلْحَلَةَ أَنَّهُ حَدَّثَهُ أَنَّ ابْنَ شِهَابٍ حَدَّثَهُ أَنَّ عَلِيَّ بْنَ حُسَيْنٍ حَدَّثَهُ أَنَّ الْمِسْوَرَ بْنَ مَخْرَمَةَ قَالَ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَخْطُبُ وَأَنَا يَوْمَئِذٍ مُحْتَلِمٌ «إِنَّ فَاطِمَةَ مِنِّي»
