Praise be to Allaah.
It is forbidden for Muslim women to marry non-Muslim men, according to the Qur’aan, the Sunnah and the consensus of the scholars (ijmaa’) (see question # 689) . If such a marriage takes place, it is invalid, it does not have any impact upon inheritances according to sharee’ah, and any children born from this union are illegitimate. Hoping that the husband may become Muslim does not alter this ruling in the slightest.
