How many times can a husband give talaq before it becomes irrevocable?

A husband is given three separate opportunities to pronounce talaq, and the first two are revocable, meaning the couple can reconcile and resume marriage either during the wife's iddah without a new nikah or even after iddah ends through a fresh nikah contract. Once the third talaq is pronounced, whether given all at once or across separate occasions, the divorce becomes final and irrevocable, and the couple cannot remarry each other unless the wife first marries someone else, that marriage ends naturally, and she completes her iddah from him too. This rule exists specifically to stop husbands from using talaq carelessly, treating it as a threat to control rather than a serious decision with real consequences. Many scholars also stress that pronouncing all three talaqs together in one sitting is strongly discouraged, since Islam intended each talaq to come with a genuine waiting period for reflection and possible reconciliation, not as a single rushed decision. Treating talaq lightly is something the Prophet ﷺ specifically warned against, since marriage was never meant to be ended on impulse. Allah knows best.
