A hindu-muslim wedding!!!

well i can't speak to what's in his heart, but i mean, he is an actor and as far as the singing/dancing thing goes, i'm pretty sure islam forbids that too... so who knows how strong his faith is or what his reasoning is? maybe its not something bugs him? its not really up to us to make the call on that, you know? nor is there a single formula to follow to resolve this.
i mean, this is a very, very personal thing, that the person converting/ marrying has to figure out for themselves.
this is easier said than done. when you want to marry someone that you love and that you know is an excellent person inside and out, you're either not religious and don't care OR you're hopeful that in the future they might "see the light".

who can say? you might be right, you might not. they say once a person says the shahadah, Allah gives them hidayat eventually even if its not right away or even if they didn't say it with full belief at first.
