What is the ruling regarding a husband uttering divorce three times, where the first was explicit, the second explicit and repeated twice, and the third conditional, when he said to his son: "If you do not stop fighting, I will tell your mother you are divorced"?

The divorce does not take effect by the husband's statement to his son, "If you do not stop fighting, I will tell your mother: you are divorced," because it is a threat to pronounce divorce, not an explicit divorce. The husband should fear Allah and avoid uttering the word of divorce unless he intends it after careful consideration and deliberation; for divorce is not for venting anger but for ending the marital relationship when there is a compelling reason to do so.
