"I said: 'O Messenger of Allah, I do not see you fasting any month as much as Shaban.' He said: 'That is a month to which people do not pay much attention, between Rajab and Ramadan. It is a month in which the deeds are taken up to the Lord of the worlds, and I like that my deeds be taken up when I am fasting."' (Using translation from Nasāʾī 2357)  

قُلْتُ يَا رَسُولَ اللهِ لَمْ أَرَكَ تَصُومُ مِنَ شَهْرٍ مِنَ الشُّهُورِ مَا تَصُومُ مِنْ شَعْبَانَ قَالَ «ذَلِكَ شَهْرٌ يَغْفُلُ النَّاسُ عَنْهُ بَيْنَ رَجَبَ وَرَمَضَانَ وَهُوَ شَهْرٌ تُرْفَعُ فِيهِ الْأَعْمَالُ إِلَى رَبِّ الْعَالَمِينَ فَأُحِبُّ أَنْ يُرْفَعَ عَمَلِي وَأَنَا صَائِمٌ»  

I said: Messenger of Allah, I do not see you fasting ˹more˺ in any month like you fast in Shaʿbān. He said, "People are heedless in that month between Rajab and Ramaḍān and it is the month where deeds are raised up to the Lord of the worlds. Therefore I prefer that my deeds are raised up while I'm fasting."  

قُلتُ: يَا رَسُولَ الله! لَمْ أَرَاكَ تَصُومُ مِنْ شَهْرٍ مِنَ الشُّهُورِ مَا تَصُومُ مِنْ شَعْبَانَ؟ قَالَ: «ذَلِكَ شَهْرٌ يَغْفُلُ النَّاسُ عَنْهُ بَيْنَ رَجبٍ وَرَمَضَانَ، وَهُوَ شَهْرٌ تُرْفَعُ فِيهِ الأعْمَالُ إِلَى رَبَ الْعَالمِينَ، فَأُحِبُّ أنْ يُرْفَعَ عَمَلِى وَأَنَا صَائِمٌ۔»
