About a month ago (sorry, this took awhile) I wrote an article on IUDs and how they work. I have since searched around for opinions on the IUD from scholars both locally and internationally. The question of whether or not the IUD is haraam or halaal comes down to a few important issues
1. What defines the start of a pregnancy?
2. What are the conditions of using reversible contraception?
3. What ruling do you take on interrupting a pregnancy (elective abortion)?
