Can a Woman in Postnatal Bleeding Marry Before Becoming Pure?

According to Hazrat Sha'bi (may Allah have mercy on him) and Hazrat Hammad (may Allah have mercy on him), it is permissible for a woman in the state of nifas (postnatal bleeding) to marry before becoming pure.

Hazrat Sha'bi (may Allah have mercy on him) and Hazrat Musayyib bin Rafi' (may Allah have mercy on him) say that a woman in nifas (postnatal bleeding) cannot marry before the bleeding stops.

Hazrat Hakam (may Allah have mercy on him) and Hazrat Hammad (may Allah have mercy on him) say that she can marry even if the bleeding has not stopped.

Hasan (may Allah have mercy on him) considered it disliked for a woman in postnatal bleeding to marry, but if she does marry, the marriage is valid.
