A:
It is not permissible to
have sexual intercourse with a woman in her postpartum period, until she performs Ghusl (ritual bath following major ritual impurity) and becomes pure of it. Allah (Exalted be He) says,
...therefore keep away from women during menses and go not unto them till they are purified (from menses and have taken a bath). And when they have purified themselves, then go in unto them as Allâh has ordained for you (go in unto them in any manner as long as it is in their vagina).
A woman in her postpartum period is like the menstruating woman. However, if the bleeding completely stops before the elapse of the forty days and she performs Ghusl (Part No. 19; Page No. 281) with water or performs Tayammum (dry ablution) with an excuse, it is permissible to have sexual intercourse with her. The Kaffarah (expiation) for having sex with a woman in her postpartum period is like that for having sex with a menstruating woman (giving a Dinar or half a Dinar in charity). May Allah grant us success. May peace and blessings be upon our Prophet, his family and Companions.
