May Allāh be good towards you, this questioner from outside also says, I have a brother that doesn’t pray and doesn’t fast, what should I do with him and he lives with me in the same house?

Shaykh Ṣāliḥ al-Fawzān:

You leave or he leaves, do not assemble with him in one house; he doesn’t pray, he doesn’t fast. This is not a Muslim so how can you live with him?
