What is the ruling on swearing an oath by divorce based on the strong presumption that the wife hung up the phone, and does divorce occur in this case?

If a husband pronounces divorce based on his assumption that his wife had hung up the phone, the divorce does not take effect. Both spouses are advised to avoid marital problems and conflicts, and to strive for understanding and respect. They should exercise wisdom and deliberation when disagreements arise. The husband, in particular, should avoid rushing to pronounce divorce and steer clear of anger.
