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 النَّاسُ إِنَّ مِنْكُمْ مُنَفِّرِينَ فَأَيُّكُمْ مَا صَلَّى بِالنَّاسِ فَلْيُجَوِّزْ فَإِنَّ فِيهِمُ الضَّعِيفَ وَالْكَبِيرَ وَذَا الْحَاجَةِ ‏"‏ ‏.‏
