Is it permissible to assist in divorcing the second wife and returning the husband to his first wife and children, knowing of his harsh treatment of the second wife and their mutual desire to reconcile?

It is not permissible to separate a man from his wife without a legitimate reason, and this is one of the major sins and an act of sorcerers and devils. The husband must be advised to treat his wife kindly and be reminded that procreation is a shared right of both spouses. Striving for the return of his first wife is commendable, and it does not necessitate separating from his second wife if he is capable of combining them. The law that prevents this is an injustice that may be overcome by legitimate means.
