My name is Helen. I'm Muslimah. As my question about my name, I heard this name is Haraam. So, my question is: If I must to change it to an Arabic name or this is not compulsory.
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad sallallaahu alayhi wa sallam is His slave and Messenger.
It is not obligatory on you to change your name into an Arabic name, and we do not see any harm in retaining your name.
The forbidden and disliked names are due to the following matters:
a) Names that imply being a slave to other than Allah, like 'Abdul-Maseeh, or 'Abdur-Rasool and the like. (i.e. slave of Jesus, slave of the Messenger).
b) Names that are exclusively for Allah or names that are among the attributes of Allah like Al-Khaaliq (The Creator), Al-'Aleem (The All-Knowing), and Maalik-ul-Mulk (The Eternal Owner of Sovereignty).
c) Names that have dispraised meanings like Harb (war) and Murrah (bitter).
d) Names that praise one's own self.
So if the name comprehends one of the previous meanings, it should be changed, otherwise it is not obligatory to change it. Also it is not obligatory on whoever embraces Islam to change his/her name except if it includes one of the previous forbidden meanings.
Allah knows best.
