A group donated land for a mosque 25 years ago when they were the majority. Now, having migrated to the area, a new group forms the majority and is attempting to take control of mosque management without the original donors' consent. The advice given is that once land is donated, it cannot be reclaimed, and the donation cannot be conditional. However, if there was a promise of involvement in administration, legal action might be possible based on long participation, but not solely on the land donation. Membership and participation in committee meetings are key to claiming a right in management.
