Q: Is there itikalf in a musalah? The imaam says we must do it. It is a rented property. Back home we were not allowed to do it in our musalah. Clarify
A: No, a musallah would not qualify for a place to do ones itikalf.
Do what Allah requires for you to do. If it is not required for you to do something, spend your energy on things requested of you by Allah (SWT). Alternatively, go to a musjid and perform your itikalf over there.
Allah Certainly Knows Best.
