What is the effect according to the Maaliki Math-hab, if the husband says to his wife: "You are haraam for me."?

Answer

If the husband is aware of the mas'alah that "You are haraam to me.", viz. it constitutes three Talaaq, then it will be three Talaaqs. He may then not marry her again unless she marries another man who divorces her after having consummated the marriage.

If the man is ignorant and unaware of the mas'alah, then it will be one Talaaq. This is in terms of the Maaliki Math-hab.
