Birth control if there is danger on the mother's life
A woman performed a tubal ligation surgery ten years ago because she used to suffer from toxemia,
hypertension, and proteinuria during pregnancy in addition to being a diabetic patient. She used to experience epileptic seizures while delivering her four children. Doctors advised her not to have anymore children. She, thus, performed a tubal ligation surgery and she did not know the ruling of Shari`ah (Islamic law) on this issue at that time. Now as Allah (Exalted be He) has endowed her with guidance and knowledge of Islam, what is she supposed to do?
If the reality is as you mentioned, there is no blame on her for having performed a tubal ligation surgery. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
