What is the jurisprudential ruling on birth control when the wife is harmed by repeated Cesarean births, and what is the sin incurred by a husband who refuses to have many children?

Contraception is divided into two categories:

First: Permanent prevention, which is not permissible unless pregnancy poses a danger to the mother's life or if she suffers from unbearable hardship because of it.

Second: Temporary postponement, which is permissible out of necessity, such as for the mother to rest between pregnancies or to raise children.

Accordingly, it is not permissible to terminate a pregnancy due to the father's desire to limit the number of children or fear of their expenses, because Allah Almighty has guaranteed sustenance, as confirmed by His saying: "We provide for them and for you" and "And there is no creature on earth but that upon Allah is its provision."
