Sahih al-Bukhari 1969 Narrated `Aisha: I never saw Allah's Messenger (ﷺ) fasting for a whole month except the month of Ramadan, and did not see him fasting in any month more than in the month of Sha'ban. الْمَرْغُوبَاتُ مِن الصِّيَامِ أَنْوَاعُ أَوَّلُهَا صَوْمُ الْمُحَرَّمِ وَالثَّانِي صَوْمُ رَجَبٍ وَالثَّالِثُ صَوْمُ شَعْبَانَ وَصَوْمُ عَاشُورَاءَ فتاوی عالمگیری ، ج:1 ، ص: 202 Translation: The Mustahab types of fasting are of several kinds. The first is fasting in Muharram, the second is fasting in Rajab, *the third is fasting in Sha'ban,* and fasting on the day of Ashura. (Fatawa Alamgiri, Vol. 1, Page 202)
