Is it obligatory for a woman in postpartum bleeding (nifas) to wait forty days to become ritually pure after childbirth for Hajj?

The postnatal period (nifas (definition)) does not exceed forty days, according to the more preponderant opinion. It depends on the presence of blood. If the blood flow stops before forty days, she becomes pure and can pray, and everything that is unlawful for a woman in nifas becomes lawful for her. As for circumambulation (tawaf (definition)), it is not valid during nifas according to the majority of scholars, but it is permissible to delay it until she becomes pure. The rest of the Hajj rituals are valid during nifas.
