As for her reason to not date this Karim, obviously, since most Muslims don’t behead people or beat their wives, not wanting to associate with people like that is a bad reason to not want to date a Muslim.
There are some good reasons why this woman might want to walk away, though, that aren’t based on less-warranted stereotypes, reasons that have to do with the realities of the ways in which sexism, misogyny, sex-negativity, patriarchy, and purity culture manifest themselves Muslim-dominated cultures.
Even if he doesn’t appear to be very religious, you should still learn about Islam.
If you marry a Muslim man, Islam will play a large part in your life, even if you have no intention of converting.
After a whirlwind relationship, he wants to marry you as soon as possible. As refreshingly different as that is from what you may be accustomed to, it is still a good idea to proceed with caution.
There are several things you should consider first, though.
As such, the permission to marry the ahl al-kitab only extends to men.
Some Muslim men choose a potential spouse who meets certain criteria. Too many non-Muslim women are caught off-guard after the wedding.3) If the people concerned are already in a relationship, is it preferable for them to get married? The permissibility of a Muslim man marrying a woman from the ahl al-kitab (‘People of the Book’) is understood from the Qur’anic verse, “It is lawful for you to marry chaste Muslim women and chaste women of the People of the Book when you have given them their dowries.” (5:5) According to most scholars, this verse specifies or abrogates a previous verse of the Qur’an (1) that prohibited men and women from marrying non-Muslim polytheists.The exception in Qur’an 5:5 was only extended to men and not to women as is clear.However it does also mean that you are taking on both the man and his values and while you don't necessarily have to agree with them (the Muslim faith does not discriminate between religions), you will have to make sure that you are happy making compromises and comfortable with your partner's views just as in any inter-religion relationship.Another important point though is that while Muslims are allowed to date non-Muslims, they are told to date 'women of the book' meaning Christians or Jews.
However it does mean taking on a very strong set of beliefs and a very different culture.
