The ruling on singling out certain days of the month of Rajab for fasting

Question:
What is your opinion, Honorable Shaykh, on fasting the first three days of Rajab, as well as the thirteenth, fourteenth, and fifteenth? May Allah reward you with good.

Answer:
It is not established from the Prophet (peace and blessings be upon him) fasting specific days, neither from the beginning, nor the end, nor the middle of the month. Rather, the month of Rajab is like the other months. If a person has a habit of fasting, he fasts in Rajab or during Rajab following his usual practice. So if it is his habit to fast Mondays and Thursdays of every week, or to fast three days of every month, or if he is consistent in fasting one day and breaking the fast the next over a long period, then the month of Rajab is included with the other months. As for singling it out for fasting and believing that it has a special virtue, this has no basis in the Shari'ah. Singling out Rajab for fasting or for prayer is considered a bid'ah (religious innovation), .
