وعن عائشة رضي الله عنها
قالت لم يكن النبي صلى الله عليه وسلم يصوم من شهر أكثر من شعبان فإنه كان يصوم شعبان كله وفي رواية: كان يصوم شعبان إلا قليلا
The Prophet (sallallahu alayhi wa sallam) did not observe voluntary Saum (fasting) so frequently during any other month as he did during Shaban. He observed Saum throughout the month of Shaban. Another narration is: He (sallallahu alayhi wa sallam) observed Saum during the whole month of Shaban except a few days.
