The general principle of this is that if one of the parents of a woman from the People of the Book is not a Person of the Book, it is not permissible for a Muslim to marry her, whether that parent is a polytheist, a Magian, or an apostate. Al-Shafi'i held this view in the case where the father is not a Person of the Book, because the child is attributed to his father, takes nobility from his status, and is ascribed to his tribe. If the mother is not a Person of the Book, he has two opinions regarding it. Our view is that she is not purely of the People of the Book, so it is not permissible for a Muslim to marry her, just as if her father were a polytheist; and because she is born between one who is permissible and one who is not, it is therefore not permissible, like the sam' (the offspring of a wolf and a hyena) and the mule. It is possible that it is permissible in all cases, due to her inclusion in the general implication of the verse that permits [marriage], and because she is a woman of the Book who is allowed to remain in her religion, so she is like one whose parents are both People of the Book. The ruling regarding one whose parents are both not People of the Book is the same as the ruling regarding one whose parent is likewise; for if she is prohibited because one of her parents is a polytheist, then it is more appropriate that she be prohibited if both are polytheists. The possibility that we mentioned there is realized here, by considering her own condition rather than that of her parents.

If she does not embrace Islam until her waiting period ('iddah) has ended, her marriage contract shall be annulled.)
