أَخْبَرَنَا مُحَمَّدُ بْنُ عَلِيِّ بْنِ الْحَسَنِ، قَالَ سَمِعْتُ أَبِي قَالَ، أَنْبَأَنَا أَبُو حَمْزَةَ، عَنْ عَاصِمٍ، عَنِ الأَسْوَدِ بْنِ هِلاَلٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ أَمَرَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم بِثَلاَثٍ بِنَوْمٍ عَلَى وِتْرٍ وَالْغُسْلِ يَوْمَ الْجُمُعَةِ وَصَوْمِ ثَلاَثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ ‏.‏
