What should be done when
    mosque furnishings are no longer needed?
Question

                Is it permissible to
      move things that have been endowed to the mosque, such as cupboards, if the mosque gets
      too crowded and the mosque no longer needs them?
Praise be to Allah.Yes, it is permissible to transfer to another mosque things that have
    been endowed, if that serves a better purpose. If the mosque no longer needs something,
    such as furnishings, cupboards, etc., we can move them to another mosque if possible,
    otherwise, we can sell them and spend the money on the mosque.
If these furnishings were supplied by the Department of Awqaaf,
    then the Department should deal with them, and do what is best.
