IslamicAnswers.com: Islamic Advice

Hello everyone,

I want to revert to Islam and become a good Muslim in the future. The meaning of my current name is "happiness." I'm wondering if I have to change my name. Also, even if I don't have to, I want to change my name.

I have two Arabic names, Mahi and Maha, in my mind that I like. I want to know whether these names are halal in Islam or not. Also, do I have to change my surname/title too? If yes, what am I supposed to change it to?

Please guide me!

Khushi
