Are phrases such as "I no longer want your daughter," or "I'm fed up with your daughter," or "I want everyone to go their separate ways" considered an allusion to divorce, especially since the husband was unaware of the rulings on allusive divorce at the time he uttered them, and he intended not to divorce when he was angry, given the existence of a contingent oath of divorce?

Such phrases are allusions (kinayah) that result in divorce if the intention is present. If there is no intention of divorce, then it does not occur. As long as the husband did not intend divorce with these phrases, nothing has occurred, and he should beware of obsessive thoughts (waswasah) regarding divorce. He is advised to treat his wife kindly and not rush to divorce her. Divorce should only be resorted to after all means of reconciliation have failed. What the husband is experiencing in terms of lack of success may be due to sins, so he should blame himself, review his relationship with Allah, renew his repentance, and increase his remembrance of Allah (dhikr) and supplication (du'a).
