Question asked to Al-Imaam Muqbil bin Haadi (may Allaah have mercy upon him)
Q. We would like from you a detailed clarity whether At-Talaaq Al-Bid'ee counts?
A. The Talaaq Al-Bid'ee counts along with the husband being sinful. If he (the husband) said: I divorce you three times (at once), then one counts (and not three), just as has come in the narration of Ibn Abbaas (may Allaah be pleased with him) inSaheeh Muslim. So the divorce counts along with the husband being sinful (for divorcing in this manner). This is the correct position. He (the husband) will be sinful if he knows that (he's not to divorce in that manner)."
Note: At-Talaaq Al-Bid'ee can be translated as "The Innovated Manner of Divorcing".
