The ruling on separating students in prayer between the older and younger ones

Question:
He says: Honorable Shaykh, may Allah grant you success. We are in a secondary school with seven hundred students, and the prayer hall is crowded, causing confusion, especially between the older and younger students. The question is: Is it permissible for us, in order to prevent harm, to have the older students pray on the upper floor with an independent imam, and the younger students pray on the ground floor with an independent imam?

Answer:
The younger ones play if they are separated and left alone. As for you, if possible, you should make one prayer hall that accommodates everyone; this is obligatory. If it is not possible and you are compelled to have two prayer halls, there is no harm. However, do not designate one specifically for the younger ones and the other for the older ones. Rather, it is the imam who, as they said, does not pray in the place of the mihrab so that no one thinks the prayer has not ended. It is the imam who changes the place, not anyone else. Yes.
