أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، عَنْ سُفْيَانَ، عَنْ بَيَانِ بْنِ بِشْرٍ، عَنْ مُوسَى بْنِ طَلْحَةَ، عَنِ ابْنِ الْحَوْتَكِيَّةِ، عَنْ أَبِي ذَرٍّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لِرَجُلٍ ‏ "‏ عَلَيْكَ بِصِيَامِ ثَلاَثَ عَشْرَةَ وَأَرْبَعَ عَشْرَةَ وَخَمْسَ عَشْرَةَ ‏"‏ ‏.‏ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ لَيْسَ مِنْ حَدِيثِ بَيَانٍ وَلَعَلَّ سُفْيَانَ قَالَ حَدَّثَنَا اثْنَانِ فَسَقَطَ الأَلِفُ فَصَارَ بَيَانٌ ‏.‏

It was narrated from Abu Dharr that the Prophet said to a man:"You should fast the thirteenth, fourteenth and fifteenth." (Hasan) Abu 'Abdur-Rahman (An-Nasai) said: This is a mistake, it is not a narration of Bayan; perhaps Sufyan said: "It was narrated to us by two (Ithnan)" and the 'Alif was dropped so it became Bayan
