The ruling on installing a barrier for the purpose of enjoining good and forbidding evil in the mosque

Question:
To something, what is the ruling on setting up a barrier in the mosque in our time for one who wants to enjoin good and forbid evil?

Answer:
There is nothing wrong with it, provided that this barrier does not cause the mosque to become narrow, does not make the mosque narrow, then there is no harm in installing a barrier or a corridor, or a barrier that is on one side behind the mosque; there is no objection to that. However, if it causes crowding for the worshippers, then it is not permissible, because the need of the worshipper takes precedence over the need of the one who enforces the rules. Yes.
