أَنَّ رَسُولَ اللهِ ﷺ مَرَّ بِقَوْمٍ قَدْ أَسَّسُوا مَسْجِدًا؛ لِيَبْنُوهُ فَقَالَ أَوْسِعُوهُ تُمْلَئُوهُ قَالَ فَأَوْسَعُوهُ 4306 أنبأ أَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا يَحْيَى بْنُ أَبِي طَالِبٍ ثنا أَبُو دَاوُدَ الطَّيَالِسِيُّ أنبأ مُحَمَّدُ بْنُ دِرْهَمٍ عَنْ كَعْبِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ عَنْ أَبِي قَتَادَةَ أَنَّ رَسُولَ اللهِ ﷺ أَتَى عَلَى قَوْمٍ مِنَ الْأَنْصَارِ وَهُمْ يَبْنُونَ مَسْجِدًا لَهُمْ فَقَالَ أَوْسِعُوهُ تُمْلَئُوهُ هَذَا حَدِيثٌ قَدِ اخْتُلِفَ فِي إِسْنَادِهِ
