My sister wants to marry a guy who is Punjabi. She does not want to convert him as muslim, because he will be doing it just for the sake of marriage, and that is wrong according to us. I think islam should be accepted by heart and only when one wants to. In this case, what would be the solution for this marriage? Can they both follow their own religion? Also, What if they do court marriage? Is it possible to do Nikah? Please let me know.
Do not marry the polytheist women, unless they come to believe (in Islam); a Muslim slave-girl is better than a polytheist woman, even though she may attract you; and do not give (your women) in marriage to polytheist men, unless they come to believe; a Muslim slave is better than a polytheist, even though he may attract you.
