The ruling on living with a brother who does not pray in the mosque

Question:
May Allah reward you. The honorable Shaykh, he says: We are three brothers, and we have families, and we live in one apartment. We are? Three brothers and we have families. We are. Families, yes, and we live in one place, and our mother is with us, and one of my brothers does not pray in the mosque. I tried to move out of the house and live in another house, but my mother does not agree. If I move out from my brothers, will that be considered undutifulness to my mother?

Answer:
This is a matter of the soul of the prayer; he has not abandoned the prayer, rather he has abandoned the prayer in congregation. So he is one who abandons an obligatory duty, but he prays. However, his abandoning the congregation is abandoning a great obligatory duty and a sin. There is no need [to move out]. So you must advise him and not leave the house. Especially if your mother wants you to stay in the house. Pleasing her is required, along with advising this brother to pray in the mosque, and persisting in advising him, perhaps Allah will guide him. Yes. As long as he prays and does not leave [the house], then it is permissible for you to stay in the house, to perform your worship and to be with him, but with disapproval of his action. But if he does not pray at all, then he is considered a disbeliever, and it is not permissible for one who is able to expel him to meet him in the house.
