Is it obligatory to divorce a wife accused of infidelity, given the presence of evidence pointing to it, while she denies the accusation and claims it is a conspiracy?

It is not permissible to accuse the wife without clear evidence, for the fundamental principle regarding a Muslim woman is her uprightness, and this is especially affirmed in the case of the wife, particularly if she denies the accusation. The husband can prevent his wife from engaging in anything that exposes her to temptation, such as her working outside the home if it involves forbidden mixing, or cutting off her internet access, or preventing her from accessing it with a password. He should also work on her religious upbringing by teaching her matters of her religion, and they should engage in shared educational programs like reciting the Quran, and he should be a good role model for her. Divorce is not advisable, especially in the absence of evidence, and if what was mentioned about her is proven, divorce is not the first solution; rather, there are reformative steps that precede it.
