Her husband is extravagant in his sins; should she be patient or seek divorce?

Question:
This is a letter from Shaykh Salih from one of our sisters. The sender says: "Alif, Yaa, Mee." She says about herself: My husband is extravagant in his sins. So, is there a sin on me if I stay with him? Or is there a sin on me if I ask him for a divorce? May Allah reward you with good.

Answer:
She is required to stay with him and advise him, unless he commits matters that necessitate apostasy from the religion of Islam, such as intentionally abandoning the prayer. In that case, it is not permissible for her to stay with him while he is not a Muslim; rather, she demands separation. If he consumes something of the forbidden things that are less than shirk (associating partners with Allah), such as intoxicants or other sins, she stays with him, but she is required to advise him with the strongest advice. If he persists and does not comply, she also has the right to seek separation. Yes.
