أَخْبَرَنَا حَفْصُ بْنُ عُمَرَ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ مَنْصُورِ بْنِ سَعْدٍ، عَنْ مَيْمُونِ بْنِ سِيَاهٍ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ صَلَّى صَلاَتَنَا وَاسْتَقْبَلَ قِبْلَتَنَا وَأَكَلَ ذَبِيحَتَنَا فَذَلِكُمُ الْمُسْلِمُ " .
