Husband says: "I am considering giving you a divorce." Wife says: "Does that mean you've given me one?" Husband says "Yes."
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
In this case, one revocable ṭalāq would be effective as the husband has concurred and confessed to giving the ṭalāq by replying “yes”.
Only Allah knows best
