Does divorce take effect if the wife goes to school after the husband swore by divorce three times that she would not go, while he was angry and intended it, then retracted his oath, and is expiation required for this oath?

Divorce pronounced in a state of anger: some types do not take effect, such as anger that causes a loss of awareness and perception, or intense anger in which a man loses control of himself due to a prolonged dispute, fight, or verbal abuse. The man himself determines the degree of his anger. As for divorcing three times with a single utterance, it counts as one divorce. If the anger did not reach a level that invalidates the divorce, it is considered one divorce, and the husband can take his wife back as long as she is within her waiting period (iddah).
