I have a few concerns regarding changing one's name to an Islamic one. I know it's not an obligation. The name I have in mind is Khalil Abdul Nasir, I just want to know if the name sounds foolish, because I'm not too keen on my Arabic. My other concern is not having my father's name in it, after a bit of reading online, I found that it is considered a sin to not represent your father in your name. Maybe I wasn't understanding, but I figured I'd come to this forum for advice. Thank you in advance.
