It was narrated that Umm Salamah said:
"The Messenger of Allah ﷺ used to pray witr with thirteen rak'ahs, but when he grew older and weaker he prayed witr with nine."
أَخْبَرَنَا أَحْمَدُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنْ يَحْيَى بْنِ الْجَزَّارِ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يُوتِرُ بِثَلاَثَ عَشْرَةَ رَكْعَةً فَلَمَّا كَبِرَ وَضَعُفَ أَوْتَرَ بِتِسْعٍ .
