37) باب أَمْرِ الأَئِمَّةِ بِتَخْفِيفِ الصَّلاَةِ فِي تَمَامٍ ‏

حَدَّثَنَا ابْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏ ‏.‏ "‏ إِذَا مَا قَامَ أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفِ الصَّلاَةَ فَإِنَّ فِيهِمُ الْكَبِيرَ وَفِيهِمُ الضَّعِيفَ وَإِذَا قَامَ وَحْدَهُ فَلْيُطِلْ صَلاَتَهُ مَا شَاءَ ‏"
