Question: Is it permissible to move property assigned as waqf for a mosque to outside the mosque for the people to use and then return them back? For example the books assigned as waqf for the mosque’s library are borrowed for studying outside the mosque. Is there a difference between the holy Qur’an, the supplication books, and other books?

There is no difference between the Holy Qur’an, supplication books, other books, and all other properties of the mosque as far as the waqf status is concerned; the criteria concerning them is that: if properties are assigned as waqf for use specifically inside the mosque, it is not permissible to take them out, otherwise, it is permissible with the permission of the shari‘ah-compliant trustee.
