Resorting to birth control due to the wife's illness

Q: My wife is in the eighth month of pregnancy and this is her ninth pregnancy. I thank Allah (Glorified be He) that the eight children she gave birth to are alive. Our standard of living improves with every child we have. However, my wife suffers a lot due to pregnancy and its reoccurrence because of some diseases that have afflicted her during our married life. Now she suffers from a contagious disease that results in a mouth ulcer and we have visited many doctors. She recovers for sometime then it returns. This disease prevents her from eating normal food. Sometimes she goes a week (Part No. 19; Page No. 305) without food and her body becomes so weak. Once she took contraceptive pills but this caused her to suffer from an allergy that remained with her till today. She asked me to allow her to have a hysterectomy surgery which she learned about from some women who have had it before. Therefore, I would like to know the Islamic ruling on my wife's request. May Allah reward you good.

A: If the reality is as you mentioned, there is no harm in her taking contraceptive pills. However, if there is another method to prevent pregnancy other than hysterectomy, it will be better so as to try the easier solution first. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
