Is the wife obligated to pray and engage in marital relations after 10 days post-childbirth and her purification? Can she become pregnant while breastfeeding naturally and not having her menstrual period? And is she required to make up delayed obligatory prayers?

Postpartum bleeding (nifas (definition)) is blood that a woman experiences after childbirth. A woman is considered pure (tahir) if the bleeding stops, even if it is after a short period, because there is no minimum limit for nifas. She should then perform ghusl (definition) (ritual bath), pray, and her husband is permitted to have intercourse with her. She does not need to wait for forty days. A pregnant and breastfeeding woman can also become pregnant again.
