(62) باب إِذَا صَلَّى لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "If anyone of you leads the people in the prayer, he should shorten it for amongst them are the weak, the sick and the old; and if anyone among your prays alone then he may prolong (the prayer) as much as he wishes. " (FR)
