[Machine] The Prophet ﷺ used to perform nine units of prayer (raka'at) in Tahajjud (night prayer). When the time of dawn approached and it was about to rise, he would perform seven units of prayer, then he would perform two units of prayer while sitting, and he would say the Taslim (completion of prayer) [at the end of those two units].  

أحمد:٢٥٩٠٠ – حَدَّثَنَا أَبُو كَامِلٍ وَعَفَّانُ قَالَا حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنْ سَعْدِ بْنِ هِشَامٍ عَنْ عَائِشَةَ

أَنَّ النَّبِيَّ ﷺ كَانَ يُوتِرُ بِتِسْعِ رَكَعَاتٍ فَلَمَّا بَدَّنَوَلَحُمَ صَلَّى سَبْعَ رَكَعَاتٍ ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُوَ جَالِسٌ قَالَ عَفَّانُ فَلَمَّا لَحُمَ وَبَدَّنَ
