(42) باب كَيْفَ الْوِتْرُ بِسَبْعٍ
Shu'bah narrated from Qatadah, from Zurarahbin Awfa, from Sa'd bin Hisham, that:
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."
