Ruling on having one’s tubes tied
Question

                I am expecting my fourth child.  I have high-risk pregnancies, according to doctors, due to physical problems.   Also, each time I have to deliver by caesarian-section, so this will be my fourth caesarian, Inshallah.   I have been advised by doctors and family members to get my tubes tied during the coming caesarian operation, so as to avoid getting pregnant again. My husband has no objection, as long as is allowed in Islam to take this step due to health risk.I feel the same way. Please, guide me because soon I have to make a decision.
Praise be to Allah. 
          Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy 
          on him) was asked a similar question, and he answered: 
 
          There is nothing wrong with the operation mentioned, 
          if the doctors have stated that getting pregnant would cause her harm, 
          so long as her husband has given permission for that. And Allaah knows 
          best.
