Does a husband's saying to his wife, "What do you think if I divorce you?" constitute a divorce?

The Sharia has placed divorce in the husband's hand, and the wife does not possess it unless her husband delegates her to divorce herself. The words mentioned in the question do not constitute a divorce, because they are merely a mention of divorce in the context of a question or an offer, or a promise of it, and not an actualization of it. Therefore, divorce does not occur by them, and the spouses must resume their lives with good companionship and respect.
