“The Messenger of Allah ﷺ used to join Sha’ban to Ramadan.” (Using translation from Ibn Mājah 1648)  

«كَانَ رَسُولُ اللهِ ﷺ يَصِلُ شَعْبَانَ بِرَمَضَانَ»  

"The Messenger of Allah used to fast until we said: 'He will not fast.' And he used to fast Shaban, or most of Shaban."' ' (Using translation from Nasāʾī 2177)  

عَنْ صِيَامِ رَسُولِ اللهِ ﷺ فَقَالَتْ كَانَ رَسُولُ اللهِ ﷺ «يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَكَانَ يَصُومُ شَعْبَانَ أَوْ عَامَّةَ شَعْبَانَ»  

"One of us (women) would miss some fasts in Ramadan and she would not be able to make it up until Shaban began, and the Messenger of Allah did not fast in any month as he fasted in Shaban; he used to fast all of it, except a little, he used to fast all of it." ' (Using translation from Nasāʾī 2178)   

أَنْ تَقْضِيَ حَتَّى يَدْخُلَ شَعْبَانُ وَمَا كَانَ رَسُولُ اللهِ ﷺ «يَصُومُ فِي شَهْرٍ مَا يَصُومُ فِي شَعْبَانَ كَانَ يَصُومُهُ كُلَّهُ إِلَّا قَلِيلًا بَلْ كَانَ يَصُومُهُ كُلَّهُ»
