The library in the Masjid (mosque) lends some valuable books and tapes to borrowers for a certain period for a nominal fee for each item. Is this permissible
or is it regarded as a business?
The books and other items in a Masjid library are regarded as Waqf (endowments). It is not permissible to charge a fee for their use. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
