(19) باب صَلاَةِ الْقَاعِدِ فِي النَّافِلَةِ وَذِكْرِ الاِخْتِلاَفِ عَلَى أَبِي إِسْحَاقَ فِي ذَلِكَ
It was narrated from Abu Salamah, that Umm Salamah said:
"The Messenger of Allah (ﷺ) did not pass away until most of his prayers were offered sitting down, except for the obligatory prayers, and the dearest of actions to him were those which were done persistently, even if they were few."
