ابن ماجة:١٠٠٧حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي الْحُسَيْنِ أَبُو جَعْفَرٍ حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ الْكِلاَبِيُّ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عَمْرٍو الرَّقِّيُّ عَنْ لَيْثِ بْنِ أَبِي سُلَيْمٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

قِيلَ لِلنَّبِيِّ ﷺ إِنَّ مَيْسَرَةَ الْمَسْجِدِ تَعَطَّلَتْ فَقَالَ النَّبِيُّ ﷺ مَنْ عَمَّرَ مَيْسَرَةَ الْمَسْجِدِ كُتِبَ لَهُ كِفْلاَنِ مِنَ الأَجْرِ
