The problem is
1.Birth control is used to have as little children as possible, as we can see in the west people now use it to just make sure they have 1 or 2 children,
2.Modern birth control in not good for a person health, and also its not good for the wider society, such as women's birth control when they urinate in toilets the hormones leak into the water and eventually find themselves back in tap water that we drink, there are many other cases this is just one example, they also mess up your bodies hormones and health
3.Birth control was made and invented to control births because of widespread zina and also to help stop Stds spreading, it was never invented for married people
As you can see in the past, unlike what Angelina said, not everyone had 11 kids, in actuality, even if we count the kids who have died before they reached the age of puberty, the amount of kids people had were around 3-5, and like the sahaba if they had multiple wives, they would have had more. Natural forms of contraception are not bad, but modern forms most definitely are and have not provided good to society.
