First two babies born with normal birth.2) Our last two children were born with cesarean.3) 5th one will be born next week with cesarean also Insha Allâh.4) Doctor says, to give birth with cesarean is allowed maximum 4 times but quite risky.5) He recommends to do operation not to have baby again (to become sterile) in the next week's cesarean. At the cesarean time with small operation they are able to do it.6) Doctor says, if she gets pregnant again, there is a risk of losing baby and also mother, but he does not give us the percentage of risk.7) I know in normal conditions, to sterilizing is not allowed in Islam8) My question is, does our situation enter the inevitable condition. 9) Please give concrete answer and solution not around solution.10) It is very important because I am seeking true solution for sake of Allah and I need answer in few days.

If the doctors who are reliable and excellent in their profession confirm that your situation requires that you stop any future pregnancy, or your life will be in danger, in this case you are permitted to act according to the advice of these specialists. This act then is not considered as cutting off the progeny, which is forbidden in Sharia. The above ruling is based on many basics of Sharia.
Allah knows best.
