The Excellence of Observing Saum (Fasting) in the months of Muharram and Sha'ban and the Secred Months
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ لَمْ يَكُنِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يصوم من شهر أَكْثَرَ مِنْ شَعْبَانَ فَإِنَّهُ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ وفي رواية: كَانَ يَصُومُ شَعْبَانَ إِلاَّ قَلِيلاً. ((مُتَّفَقٌ عَلَيْهِ))
'Aishah (May Allah be pleased with her) reported: The Prophet (ﷺ) did not observe voluntary Saum (fasting) so frequently during any other month as he did during Sha'ban. He observed Saum throughout the month of Sha'ban. Another narration is: He (ﷺ) observed Saum during the whole month of Sha'ban except a few days. [Al- Bukhari and Muslim].
