Is it permissible to use magic to retrieve a son, and will the father be questioned about it before Allah, and is it permissible to kill the mother to retrieve him?

If the wife is dissolute due to her relationship with another person, she should be called to repentance. If she repents, the marriage is preserved. If she persists, he should separate from her amicably. The mother's custody is forfeited by her dissoluteness, and custody goes to the father if he undertakes a permanent move. The father is responsible for his son's upbringing, and he must employ stratagem to free his son from this woman, such as luring her to a Muslim country and submitting the matter to the Sharia court. It is forbidden to use magic or kill the wife in order to reclaim the son. A Muslim should exercise deliberation when choosing a wife.
