حَدَّثَنَا هَنَّادٌ، قَالَ: حَدَّثَنَا عَبْدَةُ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو، قَالَ: حَدَّثَنَا أَبُو سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ: لَمْ أَرَ رَسُولَ اللهِ صلى الله عليه وسلم، يَصُومُ فِي شَهْرٍ أَكْثَرَ مِنْ صِيَامِهِ لِلَّهِ فِي شَعْبَانَ، كَانَ يَصُومُ شَعْبَانَ إِلا قَلِيلا، بَلْ كَانَ يَصُومُهُ كُلَّهُ.
'A’isha said:
"I did not see Allah’s Messenger (Allah bless him and give him peace) fast in any month more than his fasting for Allah’s sake in Sha'ban. He used to keep fast through all but a little of Sha'ban; no indeed, he used to keep fast through all of it!”
