“I asked ‘Aishah about the fasting of the Prophet ﷺ. She said: ‘He used to fast until we thought he would always fast. And he used to not fast until we thought he would always not fast. I never saw him fast more in any month than in Sha’ban. He used to fast all of Sha’ban; he used to fast all of Sha’ban except a little.’”

عَنْ صِيَامِ النَّبِيِّ ﷺ فَقَالَتْ كَانَ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ وَلَمْ أَرَهُ صَامَ مِنْ شَهْرٍ قَطُّ أَكْثَرَ مِنْ صِيَامِهِ مِنْ شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ كَانَ يَصُومُ شَعْبَانَ إِلاَّ قَلِيلاً
