Question: The basement of a masjid, which is ruled as a part of masjid in terms of waqf, has been turned into a storeroom, and the masjid authorities have decided to turn some of it into a gym as well as a place for cultural classes. Is this a problem according to The Islam's law?

Answer: In general, turning a masjid into a gym is not allowed; But there is nothing wrong with doing cultural activities that do not conflict with the masjid.
