Is a husband considered a Dayyuth if he forgives his wife and keeps her as his wife for the sake of their children, after discovering a message to her from another man in which he says: "You say you cannot live without me and without your children, so what is the solution?" and "I am ready to live under your command"?

If the wife repents of what she has fallen into, there is no harm in keeping her. However, if she repeats it or if something suspicious appears, then the husband should separate from her. Divorce in this case is either recommended or obligatory. The husband must fulfill his responsibility of guardianship over his wife, keep her away from suspicious mixing and private seclusion, compel her to dress modestly and discreetly, and teach her the matters of her religion.
