أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ، قَالَ أَنْبَأَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ فِطْرٍ، عَنْ يَحْيَى بْنِ سَامٍ، عَنْ مُوسَى بْنِ طَلْحَةَ، عَنْ أَبِي ذَرٍّ، قَالَ أَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نَصُومَ مِنَ الشَّهْرِ ثَلاَثَةَ أَيَّامِ الْبِيضِ ثَلاَثَ عَشْرَةَ وَأَرْبَعَ عَشْرَةَ وَخَمْسَ عَشْرَةَ ‏.‏
