وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ أَبِي عُمَيْسٍ، عَنْ قَيْسِ بْنِ مُسْلِمٍ، عَنْ طَارِقِ بْنِ شِهَابٍ، عَنْ أَبِي مُوسَى، - رضى الله عنه - قَالَ كَانَ يَوْمُ عَاشُورَاءَ يَوْمًا تُعَظِّمُهُ الْيَهُودُ وَتَتَّخِذُهُ عِيدًا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ صُومُوهُ أَنْتُمْ ‏"‏ ‏.‏
