Q: I read in “Sahih Al-Jami‘” Hadith no. 397
verified by Al-Albany and reported by Al-Suyuty no. 398, which he ranked as Sahih (authentic), on the authority of Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: When Sha‘ban is half over, do not fast until the advent of Ramadan. There is also another Hadith reported by Al-Suyuty no. 8757, ranked as Sahih and verified by Al-Albany in “Sahih Al-Jami‘” no. 4638 on the authority of `Aishah (may Allah be pleased with her) that she said: The most beloved of months for him (peace be upon him) to fast in was Sha‘ban which was continuous with his Sawm (Fasting) in Ramadan. How can we reconcile the two Hadiths?
A: Bismillah [In the Name of Allah], and all praise be to Allah, to proceed; the Prophet (peace be upon him) used to fast the whole of Sha‘ban except for a few days, as authentically reported from the Hadith of `Aishah and Um Salamah. As for the Hadith that prohibits observing Sawm after the middle of Sha‘ban, it is Sahih as mentioned by the knowledgeable brother, Shaykh Nasir Al-Din Al-Albany. What is meant is that it is not permissible to start fasting after halfway through the month of Sha‘ban, but if a person fasts most of or all of the month, they will be acting upon the Sunnah (whatever is reported from the Prophet). Allah is the Grantor of success!

The fourth question of Fatwa no. 7912
Q 4: Is it permissible to observe Sawm (Fasting) on Mondays and Thursdays of Rajab and Sha‘ban? Is it permissible to observe Sawm after the fifteenth of Sha‘ban?
A: Observing Sawm on Mondays and Thursdays is not only restricted to Rajab or Sha‘ban, rather it is a Mandub (commendable) act during all the months of the year. It is also permissible for whoever is in the habit of fasting them all year to observe fasting them after the fifteenth of Sha‘ban, even if one of these days coincides with the Day of Doubt (so called because there is doubt concerning it – is it the last day of Sha‘ban or the first day of Ramadan), for the Prophet (peace be upon him) said: Do not observe fast for a day or two days ahead of Ramadan, except a person who is in the habit of observing a particular Sawm; they may fast on that day. (Agreed upon its authenticity by Al-Bukhari and Muslim)
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family, and Companions!
