What is the ruling on playing cards (baloot) in an apartment rented for the purpose of prayer, gatherings, and remembrance, and is it permissible to sit with the players?

It is not permissible to play in the musalla (prayer area), as it is a waste of time. However, if abandoning this play would lead to young people turning to something worse, such as theaters and dance halls, then it is permissible for them to engage in this play, which distracts them from sins. But this should not be in the musalla; rather, it should be in suitable places like clubs and parks.
