Building a hall in the basement of the Musjid

We discourage a multipurpose hall in the vicinity of the musjid, for it is possible for some type of a nikaah ceremony to be held there and there may be a mixed gathering or a gathering of women at some point in time. These types of get-togethers can coincide with namaaz times resulting in quite a bit of disturbance or distraction to musallees, either in the parking or at the entrances or at some point or the other.

And Allah Ta'ala (الله تعالى) knows best.
