أَخْبَرَنَا الْحَسَنُ بْنُ مُحَمَّدٍ، عَنْ حَجَّاجٍ، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي عُثْمَانُ بْنُ أَبِي سُلَيْمَانَ، أَنَّ أَبَا سَلَمَةَ، أَخْبَرَهُ أَنَّ عَائِشَةَ أَخْبَرَتْهُ أَنَّ النَّبِيَّ صلى الله عليه وسلم لَمْ يَمُتْ حَتَّى كَانَ يُصَلِّي كَثِيرًا مِنْ صَلاَتِهِ وَهُوَ جَالِسٌ .
Abu Salamah narrated that Aishah told him: "The Prophet (ﷺ) did not die until most of his prayers were offered sitting down."
