أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا أَبُو النَّضْرِ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ عَاصِمٍ، عَنِ الأَسْوَدِ بْنِ هِلاَلٍ، عَنْ أَبِي هُرَيْرَةَ، رضى الله عنه قَالَ أَمَرَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم بِنَوْمٍ عَلَى وِتْرٍ وَالْغُسْلِ يَوْمَ الْجُمُعَةِ وَصِيَامِ ثَلاَثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ ‏.‏
