Sunan ad-Darimi

Lady Umm Salamah (may Allah be pleased with her) said that women experiencing postnatal bleeding during the time of the Messenger of Allah (peace and blessings be upon him) would remain (in seclusion) for forty days or forty nights, and some of us would apply wars (a type of herb) to the spots on our faces.

It is narrated from Muawiyah bin Qurrah that the wife of Aaidh bin Amr reported: She came after twenty days in the state of nifas (postnatal bleeding) and got into her husband's blanket. Aaidh said, "Who is this?" She replied, "I am your wife, I have become pure." So he struck his wife with his foot and said, "Do not deceive me in my religion; wait until forty days have passed." In Dar Qutni and Musannaf, it is mentioned that she had come to him after taking a bath.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Women experiencing postnatal bleeding will remain (in that state) for approximately forty days.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them): Women experiencing postnatal bleeding will wait for forty days.

Mu'tamir bin Sulayman narrated from his father that Imam Hasan al-Basri, may Allah have mercy on him, said regarding the woman in nifas: If she sees blood, she should wait for forty days, then perform prayer. The narrator said: And Imam Sha'bi, may Allah have mercy on him, said: She should wait for two months, then she will be under the ruling of a mustahadah (woman with irregular bleeding).

Makhul said: A woman in postpartum bleeding will wait thirty days for the birth of a boy and forty days for a girl. Marwan said: This is also the statement of Sa'id bin Abdul Aziz. Imam Awza'i, may Allah have mercy on him, said: Both boy and girl are the same (i.e., the period of postpartum bleeding is forty days, during which she will be considered like a menstruating woman).

Imam Hasan, may Allah have mercy on him, said: If a woman sees blood one or two days before labor pains, then it is the blood of nifas (postnatal bleeding).

It is narrated from Ata (may Allah have mercy on him) regarding a pregnant woman, that if she experiences bleeding at the time of labor pains, then she (the pregnant woman) will do what a woman experiencing istihada (irregular bleeding) does.
