Aishah said: "When the Messenger of Allah ﷺ grew old and put on weight, he prayed seven rak'ahs and only sat in the last of them, and he prayed two rak'ahs while sitting after saying the taslim, and that was nine, O my son! And when the Messenger of Allah ﷺ offered any prayer he liked to persist in doing so." (Using translation from Nasāʾī 1718)   

الكبرى للنسائي:١٤١٢ – أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ قَالَ أَخْبَرَنَا خَالِدٌ قَالَ حَدَّثَنَا سَعِيدٌ قَالَ حَدَّثَنَا قَتَادَةُ عَنْ زُرَارَةَ بْنِ أَوْفَى عَنْ سَعْدِ بْنِ هِشَامٍ أَنَّ عَائِشَةَ قَالَتْ

لَمَّا أَسَنَّ رَسُولُ اللهِ ﷺ وَأَخَذَ اللَّحْمَ «صَلَّى سَبْعَ رَكَعَاتٍ لَا يَقْعُدُ إِلَّا فِي آخِرِهِنَّ ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُوَ قَاعِدٌ بَعْدَمَا يُسَلِّمُ فَتِلْكَ تِسْعٌ» وَكَانَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى صَلَاةً أَحَبَّ أَنْ يُدَاوِمَ عَلَيْهَا خَالَفَهُ هِشَامٌ
