أبو داود:٧٩٦حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ عَنْ بَكْرٍ يَعْنِي ابْنَ مُضَرَ عَنِ ابْنِ عَجْلاَنَ عَنْ سَعِيدٍ الْمَقْبُرِيِّ عَنْ عُمَرَ بْنِ الْحَكَمِ عَنْ عَبْدِ اللَّهِ بْنِ عَنَمَةَ الْمُزَنِيِّ عَنْ عَمَّارِ بْنِ يَاسِرٍ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الرَّجُلَ لَيَنْصَرِفُ وَمَا كُتِبَ لَهُ إِلاَّ عُشْرُ صَلاَتِهِ تُسْعُهَا ثُمُنُهَا سُبُعُهَا سُدُسُهَا خُمُسُهَا رُبُعُهَا ثُلُثُهَا نِصْفُهَا
