I believe in the old and new testament.
What category of questions does this question fit best in?
If you mean in marriage wise, that is haram (forbidden). She may not marry a non Muslim, even if he is a monotheist. But friend wise I am not really sure. It depends on her, but of course there are some things that she may want to avoid. In Islam, a man and a woman may not be alone together unless they are related or married. You must have another friend there. Also, she may not want to be touched or hugged (some Muslims are more lax on this, but others believe in absolutely no physical contact).
Not here, you're going to get really biased answers.
But good luck anyway.
It also depends on how devote she is and what sect she follows. Ultimately, if she's open to people of other religions and assuming you are (i.e. you wouldn't force her to convert either), the best thing you can do is respect her choice of religion. This means not only allowing her to practice as she sees fit but also learning enough about Islam to understand why she might be doing whatever she's doing. For instance, if she wants to honor a holiday or not eat certain things, you need to respect that. If she decides she wants to relax or potentially not follow certain tenets of Islam, it should be up to her to decide. It shouldn't be because you've either chided her or otherwise forced her to decide.
Nothing says it can't work (my parents are of completely different faiths but they also aren't very orthodox/strict so it rarely caused issues) but in order for it to work, both parties (you and her) have to be willing to make it work.
And, as a footnote, if she wants to follow the first poster's path and follow Islam to the letter, then you need to respect that (i.e. you would need to give her up).
Sorry dude you cant marry her Well unless SHE converts but most likely not but dont worry theres someone out there for you ^_^
We Muslims also believe the original scriptures (Torah, Psalms and the Gospel). So I suggest you consider Islam and learn about it. If you decide to convert, then hopefully she will accept you as future partner.
I recommend "the deen show". Watch their videos and Judge for yourself. Also read their page for FAQ on Islam:
May Allah guide you.
Important to you how? In a romantic sense? Respect her and respect her faith and leave her alone. You believing in the old and new testaments means what exactly? That you worship Jesus (pbuh)? A Muslim women can only ever marry a Muslim man. A Muslim male or female, are not permitted premarital relationships with other Muslims never mind non Muslims.
If she is important you to then do not do or say anything that would compromise her or put her in an uncomfortable position. When someone is important to you, you put their needs above your own.
I have no experience with this situation but a woman is a woman regardless of religion so my guess would be with respect ,understanding & acceptance .Just treat he who you would any other woman you where interested in but take it slow .
I would also advise you to make sure you know what you are getting yourself in for , don't set her or yourself up for heart break.
All the best.
