Fasting (Kitab Al-Siyam)
14/60. Chapter:
How The Prophet (saws) Would Fast
Sunan Abi Dawud
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِمَعْنَاهُ . زَادَ كَانَ يَصُومُهُ إِلاَّ قَلِيلاً بَلْ كَانَ يَصُومُهُ كُلَّهُ .
The tradition mentioned above has alos been transmitted by Abu Hurairah through a different chain of narrators to the same effect. This version adds: He would fast all but a little of Sha'ban, rather he used to fast the whole of Sha'ban.
