Is a divorce pronounced against a wife while she is menstruating valid, and what are the implications of this after the couple has been married?

Divorcing one's wife while she is menstruating is forbidden by the Qur'an, the Sunnah, and the consensus of Muslims; it is an innovated divorce (bid'i talaq). The Sunnah is to divorce her during a period of purity in which he has not had intercourse with her, or while she is pregnant and her pregnancy is evident. Scholars have differed on whether the divorce takes effect if he divorces her while she is menstruating. The majority of them, including the four imams, hold that it does take effect. Based on this, your divorce of your wife has taken effect. You must be patient and not hasten in the future.
