Is it permissible for a person and his wife to reside in an accommodation attached to a Quranic school within the mosque's walls?

It is permissible for a teacher, an Imam, or others to reside with their wives in a dwelling built within the mosque's enclosure and separated from it. The Permanent Committee has issued a fatwa permitting the construction of a house for the Imam and the muezzin on a portion of the mosque's land.
