Hasan (may Allah have mercy on him) says that the woman in nifas will refrain for forty days, then she will perform ghusl and offer prayers. Sha’bi (may Allah have mercy on him) says that she will refrain for two months, then she is like a mustahadah.

Hasan (may Allah have mercy on him) says that the period of nifas (postnatal bleeding) will not exceed forty days. Ata (may Allah have mercy on him) says that it will last according to her usual duration, and it will not exceed forty days.

Hazrat Ibn Abbas (may Allah be pleased with them) said that a woman in postnatal bleeding will refrain for forty days.

Hazrat Umm Salamah (may Allah be pleased with her) narrates that in the time of the Messenger of Allah (peace and blessings be upon him), women in postnatal bleeding would refrain (from prayer, etc.) for forty days, and we used to apply a yellow herb called wars to our faces because of the dull redness.

Hazrat Ubaidullah bin Abi Ziyad (may Allah have mercy on him) asked Hazrat Abdullah bin Abbas (may Allah be pleased with them both) that if a man buys a slave woman and she is pregnant, can he have intercourse with her? He replied, "No." Then he recited the verse of the Holy Qur'an: "The waiting period of pregnant women is that they give birth to their child."

Hazrat Dawood, may Allah have mercy on him, says that I asked Hazrat Sha’bi, may Allah have mercy on him, that Hazrat Abu Musa, may Allah be pleased with him, had said on the day of the conquest of Tustar that no intercourse should be had with a pregnant woman and there should be no sharing in the offspring of the polytheists, because the water (semen) increases in the child. Did he say this from his own opinion or did he narrate it from the Messenger of Allah, peace and blessings be upon him? He replied that the Messenger of Allah, peace and blessings be upon him, had said on the day of the conquest of Autas that no intercourse should be had with a pregnant woman before the birth of her child, and with other women until it is known that their wombs are empty.

It is narrated from Hazrat Abu Qilabah (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever has intercourse with a pregnant woman is not one of us.
