The Book of Fasting
Making up fasts on behalf of the deceased
وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَطَاءٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، - رضى الله عنه - قَالَ كُنْتُ جَالِسًا عِنْدَ النَّبِيِّ صلى الله عليه وسلم . بِمِثْلِ حَدِيثِ ابْنِ مُسْهِرٍ غَيْرَ أَنَّهُ قَالَ صَوْمُ شَهْرَيْنِ .
'Abdullah b. Buraida (Allah be pleased with him) reported on the authority of his father: I was sitting with the Messenger of Allah (ﷺ) ; the rest of the hadith is the same but with this variation that the (the narrator) said:" Fasts of two months."
