It is permissible to have one’s tubes tied (Tubal Ligation – Tubectomy) to prevent pregnancy as long as this procedure is temporary (reversible) and would not lead to a woman being permanently unable to conceive nor would this act cause any sort of life-threatening conditions. In addition, once the tubes have been re-opened, she would once again have the ability to conceive. In other than this scenario, it would not be permissible to perform the Tubectomy.
