Chapter 82: Mentioning The Differences Reported From Abu 'Uthman In The Hadith Of Abu Hurairah Regarding Fasting Three Days Out Of Each Month - كتاب الصيام
أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمٍ، قَالَ أَنْبَأَنَا حِبَّانُ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ عَاصِمٍ، عَنْ أَبِي عُثْمَانَ، عَنْ رَجُلٍ، قَالَ أَبُو ذَرٍّ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ صَامَ ثَلاَثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ فَقَدْ تَمَّ صَوْمُ الشَّهْرِ أَوْ فَلَهُ صَوْمُ الشَّهْرِ " . شَكَّ عَاصِمٌ .
Abu 'Uthman reported from a man, that Abu Dharrr said:
"I heard the Messenger of Allah say: "Whoever fasts three days of each month has fasted the month in full' or 'will have (the reward of) fasting the month."' 'Asim was in doubt.
