Q&A: Mosque

Answer

If the particular land was considered as Waqf (endowment) before the commencement of the building as a mosque, then all of the building, including the basements, and the levels above, have the rulings of a mosque. However, if the land was not considered as Waqf (endowment) and after completion of the building, one of the levels was considered as a mosque, then only that level will be considered as a mosque, and the rulings of the mosque will comply. Thus, those who are in the state of ritual impurity, may make use of the other levels of the building, and not enter the level considered as the mosque.

Answer

Based on obligatory precaution, it is not permissible for them [i.e., non-Muslims] to enter the mosque (masjid). As for their entering the places of worship, etc, there is no problem in it. If their entry [in imambargah or a husayniyya or a center] without hijãb is considered as a sign of disrespect, hijãb should be enforced on the [non-Muslim] women.
