"The Messenger of Allah ﷺ used to pray witr with nine rak'ahs, then he would pray two rak'ahs sitting down. When he grew weaker he prayed witr with seven rak'ahs, then he prayed two rak'ahs sitting down." (Using translation from Nasāʾī 1722)   

أحمد:٢٥٣٤٦حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنْ قَتَادَةَ عَنِ الْحَسَنِ قَالَ أَخْبَرَنِي سَعْدُ بْنُ هِشَامٍ

أَنَّهُ سَمِعَ عَائِشَةَ تَقُولُ كَانَ رَسُولُ اللهِ ﷺ يُوتِرُ بِتِسْعِ رَكَعَاتٍ وَرَكْعَتَيْنِ وَهُوَ جَالِسٌ فَلَمَّا ضَعُفَ أَوْتَرَ بِسَبْعٍ وَرَكْعَتَيْنِ وَهُوَ جَالِسٌ
