حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، حَدَّثَنَا قَيْسُ بْنُ أَبِي حَازِمٍ، عَنْ أَبِي مَسْعُودٍ ـ رضى الله عنه ـ قَالَ أَتَى رَجُلٌ النَّبِيَّ صلى الله عليه وسلم فَقَالَ إِنِّي لأَتَأَخَّرُ عَنْ صَلاَةِ الْغَدَاةِ مِنْ أَجْلِ فُلاَنٍ مِمَّا يُطِيلُ بِنَا قَالَ فَمَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم قَطُّ أَشَدَّ غَضَبًا فِي مَوْعِظَةٍ مِنْهُ يَوْمَئِذٍ قَالَ فَقَالَ " يَا أَيُّهَا النَّاسُ إِنَّ مِنْكُمْ مُنَفِّرِينَ، فَأَيُّكُمْ مَا صَلَّى بِالنَّاسِ فَلْيَتَجَوَّزْ، فَإِنَّ فِيهِمُ الْمَرِيضَ وَالْكَبِيرَ وَذَا الْحَاجَةِ ".
A man came to the Prophet (ﷺ) and said "I keep away from the morning prayer only because such and such person prolongs the prayer when he leads us in it. The narrator added: I had never seen Allah's Apostle more furious in giving advice than he was on that day. He said, "O people! There are some among you who make others dislike good deeds) cause the others to have aversion (to congregational prayers). Beware! Whoever among you leads the people in prayer should not prolong it, because among them there are the sick, the old, and the needy." (See Hadith No. 670, Vol 1)
