البخاري:١١٦٥حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَمَّتِهِ عَمْرَةَ عَنْ عَائِشَةَ ؓ قَالَتْ

كَانَ النَّبِيُّ ﷺ ح وَحَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ حَدَّثَنَا زُهَيْرٌ حَدَّثَنَا يَحْيَى هُوَ ابْنُ سَعِيدٍ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَمْرَةَ عَنْ عَائِشَةَ ؓ قَالَتْ كَانَ النَّبِيُّ ﷺ يُخَفِّفُ الرَّكْعَتَيْنِ اللَّتَيْنِ قَبْلَ صَلاَةِ الصُّبْحِ حَتَّى إِنِّي لأَقُولُ هَلْ قَرَأَ بِأُمِّ الْكِتَابِ
