حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَی أَخْبَرَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنِي يُونُسُ عَنْ ابْنِ شِهَابٍ قَالَ أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُا قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا صَلَّی أَحَدُکُمْ لِلنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِي النَّاسِ الضَّعِيفَ وَالسَّقِيمَ وَذَا الْحَاجَةِ
صحیح مسلم · Hadith 1048
Hammam b. Munabbih reported: This is what Abu Huraira transmitted to us from Muhammad the Messenger of Allah ( صلی اللہ علیہ وسلم ), and he narrated (some) ahadith out of (these narrations and one of them is this): The Messenger of Allah ( صلی اللہ علیہ وسلم ) said: When any one of you stands to lead people In prayer, he should shorten it, for amongst them are the aged, and amongst them are the weak, but when he prays by himself, he may prolong his prayer as he likes.
