Hadith on Salat: Imam should lighten prayer for sick, elderly with him

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “If one of you leads people in prayer, let him lighten it as among them are the weak, sick, and elderly. If one of you prays by himself, let him pray for as long as he wishes.

عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا صَلَّى أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفْ فَإِنَّ مِنْهُمْ الضَّعِيفَ وَالسَّقِيمَ وَالْكَبِيرَ وَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ
