What is the ruling on family planning or taking the contraceptive pill?

Family planning by temporary methods such as the pill, injections or an IUD is permissible, with mutual consent and without harm.
Its basis is the practice of ʿazl in the Prophet's ﷺ time, which was not forbidden. Accepted purposes include spacing births, protecting the mother's health and ensuring children can be raised well. But it must not be driven solely by fear of poverty or by an absolute rejection of offspring. Seek a doctor's advice to choose a safe method. Also refer to your state's fatwa. See Fertility & IVF.
