People always said birth control is only allowed if the husband permits it, not in general (before marriage) and that Islam highly dislikes it. Is this true?
There is no need to make a big deal of a husband’s permission in such a matter. Whether you are a Muslim or non-Muslim wife, of course going on birth control should be a decision made after consultation with the husband and his agreement. If you do not consider your husband worth consulting in this matter, then there is a problem with your marriage.
As for Islam having a negative view of birth control, that is not true. As I discuss in this new blog post, the hadith in which the Prophet 
seems to express a negative view of birth control is not very firmly established. And even if we take it seriously, he mere says that there is no harm in not using birth control. He does not say that birth control is harmful.
