What is Islam's position on Muslim women who commit immorality and claim to be Muslims? And what should we do concerning them? And is it permissible for someone who does not possess academic qualifications to transmit religious lectures and lessons from the Internet and deliver them to sisters in the mosque?

We thank you for your zeal for the religion, as it is a requirement of faith. We emphasize the obligation to denounce wicked women and to instill in them the fear of Allah the Almighty, reminding them that death comes suddenly and that Allah will question them about their deeds. Indeed, "Religion is naseeha (sincere advice)." As for some of them saying that practicing vice is easier than earning lawful sustenance, this is a perversion of fitra (innate disposition) and a forgetfulness of Allah. This could lead to theal of major sins and disbelief. As for da'wah (inviting to Islam), naseeha (sincere advice), enjoining good, and forbidding evil, this is for anyone who knows from the Sharia what to invite to or forbid, and it is not restricted to the people of fatwa. Practicing da'wah to Allah is a cause for steadfastness. As for your fear for your children, it is valid, and you must fortify them with beneficial knowledge, strengthen their religious deterrent, raise them to be mindful of Allah, and pay attention to their friends, for a companion is an attractor. If you are unable to display the rituals of your religion and protect yourself from doubts and desires, and it is possible for you to migrate to Muslim lands, then migration is obligatory upon you.
