باب ما جاء فى صوم رسول الله صلى الله عليه وسلمChapter: What has been reported concerning the fasting of the Messenger of Allah (ﷺ)
Fasting most of Sha'ban was the Prophet's practice
Hadith 301
حَدَّثَنَا هَنَّادٌ قَالَ: حَدَّثَنَا عَبْدَةُ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو قَالَ: حَدَّثَنَا أَبُو سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ: «لَمْ أَرَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَصُومُ فِي شَهْرٍ أَكْثَرَ مِنْ صِيَامِهِ لِلَّهِ فِي شَعْبَانَ، كَانَ يَصُومُ شَعْبَانَ إِلَّا قَلِيلًا بَلْ كَانَ يَصُومُهُ كُلَّهُ»
It is narrated from Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she says: I did not see the Messenger of Allah (peace and blessings be upon him) fasting in any month more than in Sha'ban. He would fast in most of Sha'ban, rather he would fast the entire month of Sha'ban except for a little.
