Q: We want to submit an application for buying a piece of land under my name, as I will contribute some money towards its price as well as some benevolent men who will also contribute to its price. The area of the land is small as it amounts to 150 square meters. We will, In sha’a-Allah (if Allah wills) build a Masjid (mosque) that consists of two floors; the first will be for men and the second for women. Furthermore, the Masjid is located in a low-class area in which there are many schools and other old houses, and more Masjids can be built in this area as it exists near a highway which is 15 meters wide, and another subsidiary road which is 7,30 meters wide. Is it permissible, Your Eminence, to build other floors above the two floors allocated for the Masjid, and make use of them as apartments offered for rent? The Masjid consists of only two floors, and I want to build another three or four floors to use them as apartments offered for rent, given that the piece of land will be registered under my name, and some benevolent people will donate the rest of the expenses concerning paying the price of the land and building the Masjid. You should note that such Masjids have spread abundantly in countries, such as Egypt, Sudan and others, is this permissible? Please advise, may Allah reward you.
