ابن ماجة:١١٥١حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ حَدَّثَنَا أَزْهَرُ بْنُ الْقَاسِمِ ح وَحَدَّثَنَا بَكْرُ بْنُ خَلَفٍ أَبُو بِشْرٍ حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ قَالاَ حَدَّثَنَا زَكَرِيَّا بْنُ إِسْحَاقَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أُقِيمَتِ الصَّلاَةُ فَلاَ صَلاَةَ إِلاَّ الْمَكْتُوبَةُ حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ أَيُّوبَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ
