Whoever leads people (in Prayer), let him make it short Sunan Ibn Majah 984
Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ قَيْسٍ، عَنْ أَبِي مَسْعُودٍ، قَالَ أَتَى النَّبِيَّ ـ صلى الله عليه وسلم ـ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي لأَتَأَخَّرُ فِي صَلاَةِ الْغَدَاةِ مِنْ أَجْلِ فُلاَنٍ لِمَا يُطِيلُ بِنَا فِيهَا . قَالَ فَمَا رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَطُّ فِي مَوْعِظَةٍ أَشَدَّ غَضَبًا مِنْهُ يَوْمَئِذٍ " يَا أَيُّهَا النَّاسُإِنَّ مِنْكُمْ مُنَفِّرِينَ فَأَيُّكُمْ مَا صَلَّى بِالنَّاسِ فَلْيُجَوِّزْ فَإِنَّ فِيهِمُ الضَّعِيفَ وَالْكَبِيرَ وَذَا الْحَاجَةِ "
Translation
It wasnarrated that Abu Mas’ud said
“A man came to the Prophet(ﷺ)and said: ‘O Messenger of Allah! I stay behind and do notperformthe morning prayer (in congregation) because of so-and-so, forhemakes it too long for us.’ I never saw the Messenger of Allah (ﷺ)preaching with such anger as he did that day. He said; ‘O people!There are among you those who repel others. Whoever among you leadsothers in prayer, let him keep it short, for among them are those whoare weak and elderly, and those who have pressing needs.’”
