Delaying pregnancy due to breastfeeding

Q 3: My wife starts menstruating forty days after childbirth and as a result she may conceive again. Is it permissible for her to use contraceptives to be able to breast-feed her baby? (Part No. 19; Page No. 325)

A: It is permissible for her to take contraceptive pills to delay conception in cases of necessity, such as when her health cannot bear pregnancy or if the newborn baby may be harmed by another pregnancy. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
