Do the actions of the wife—such as abandoning the hijab, ceasing to eat halal slaughtered meat, and drinking alcohol—not remove her from Islam? And in this case, does the husband bear no responsibility before God for divorcing her?

Whoever's Islam has been established with certainty is not divested of it except by a certainty equal to it. And removing the hijab (definition), consuming forbidden slaughtered meat, and drinking alcohol are grave abominations, but they do not expel their perpetrator from Islam unless they deem them permissible. It is advised to be patient with the wife and to continue advising her gently, reminding her of God, and that religion is a Muslim's most valuable asset. If she is restricted in her country, she can emigrate to a Muslim country where she can practice her religion. Divorce is disliked unless there is a need for it, and if there is a need for it, then it is permissible.
