What is the correct approach to dealing with a brother who is lax in prayer and does not pray in the mosque?

Question:
He says: Honorable Shaykh, may Allah grant you success, I have a younger brother who lives with me in my house, but he does not pray with the congregation in the mosque, as he is sleeping for most of his time. I testify to Allah that I have informed him, warned him, and threatened him, and I do not go to the mosque unless I have woken him up, but he makes excuses with sleep. He does not deny the obligation of prayer, but he is lax and lazy in it. The question is: What should I do? Do I have the right to expel him from the house? Or do you advise me to be patient with him?

Answer:
We advise you to be patient with him while taking action against him. Do not go to the mosque unless he is with you. Do not wake him up and then go; do not go to the mosque unless he is with you, until he gets used to going. When he sees your seriousness and firmness from you, he will get used to this. However, if he is displeased with your leniency in that you go and leave him, he will continue with his behavior. So, do not go to the mosque unless he is with you, once, twice, three times, then he will get used to it and realize the seriousness. Yes.
