The reward of a waqf (endowment) if the mosque is demolished and rebuilt

The questioner:
This question asks whether the waqf (endowment) is cut off or whether it continues even if the specific object of the waqf, such as a mosque, is demolished and then rebuilt.

The Shaykh:
If the mosque is demolished, the land remains a waqf (endowment), and the reward continues. The person who builds it receives the reward for the construction. Yes.

The questioner:
Even if the land was not owned by the first person.

The Shaykh:
No, if it was not owned by the first person, it reverts to the ownership of the state. Building mosques is among the state's duties, so it becomes part of the public domain.

The questioner:
But the question is about the first mosque that he built and then was demolished: does his reward continue or is it cut off?

The Shaykh:
If it was not his land, he has the reward for the construction. If the construction is removed, his reward for the future is cut off, but the reward for what has already passed continues for him, if Allah wills. Yes.
