Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

In general, it is permissible to use birth control to prevent pregnancy, and it is (also) permitted to use the (various) forms of birth control. This is based on Jabir’s saying, “‘We used to practice coitus interruptus during the time of the Messenger of Allah when the Qur’an was being revealed.” (Ibn Majah) It is graded as an authentic hadith.

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.

Allah Almighty knows best.
