حَدَّثَنَا أَبُو سَعِيدٍ يَعْنِي مَوْلَى بَنِي هَاشِمٍ قَالَ حَدَّثَنَا حُصَيْنُ بْنُ نَافِعٍ قَالَ حَدَّثَنَا الْحَسَنُ عَنْ سَعْدِ بْنِ هِشَامٍ أَنَّهُ وَفَدَ عَلَى أُمِّ الْمُؤْمِنِينَ عَائِشَةَ فَسَأَلَهَا عَنْ صَلاَةِ رَسُولِ اللَّهِ ﷺ فَقَالَتْ كَانَ يُصَلِّي مِنَ اللَّيْلِ ثَمَانَ رَكَعَاتٍ وَيُوتِرُ بِالتَّاسِعَةِ وَيُصَلِّي رَكْعَتَيْنِ وَهُوَ جَالِسٌ مُخْتَصَرٌ
