Indonesian Council of Ulama Fatwa No. 34 of 2013 on Usage of Mosques

This fatwa states that a mosque may be used as, for example, an educational facility, meeting room, or child recreation centre, provided that such activities:

  1. do not contravene shari'a;
  2. always respect the mosque; and
  3. do not disturb those praying or performing other rituals (ibadah).

Similarly, hiring out parts of a mosque for wedding receptions, for example, is permitted provided the mosque is treated with respect in the process. These conditions apply to land and objects donated pursuant to a waqf as well.
