The ruling on tying the fallopian tubes after a cesarean section

Question : A woman says that she gave birth to three children through cesarean sections, and now she is pregnant with her fourth child, and she must give birth via a cesarean section. Is it permissible for her to tie her fallopian tubes after the birth, or not?

Answer : The answer is that it is not permissible for her, because tying them means the complete cessation of childbearing. However, if it is temporary, there is no harm in doing so until she recovers and becomes strong enough for natural delivery.
