I wish to observe a recommended fast in Rajab and Shaban, however, I have a missed fast to make up from the month of Ramadan. Which one should I perform? Can the two be combined?
It is not permissible to observe a recommended fast if you have to make up a missed fast from the month of Ramadan. However, there is no problem in making up the missed fast on a day in which it is recommended to fast with the hope of earning the reward for both.
