Ruling 2425 — Marriage

If a person marries a woman while he is in the state of iḥrām (iḥrām is one of the requirements of hajj),[4] the marriage contract is invalid even if the woman is not in the state of iḥrām herself. In the event that he knew that marrying a woman [in the state of iḥrām] was unlawful for him, he can never marry that woman.
