It is something easy in sha’ Allah.
Break your fast with them and then go to the masjid.
Dear sheikh I want to do iftar in the mosque, but my parents and brothers wont allow me to break my fast there. They say break the fast in home and then go to mosque for salaah. Also i can’t join the first row in the mosque, because my house is a bit far from the the mosque. What should i do Ya Sheikh?
