Q. Is it necessary to change a Muslim revert’s non-Muslim name to a Muslim name for a Nikah to be valid?
A. Once a person accepts Islam, he/she should be given a suitable Muslim name.
If however, a person is not given a suitable Muslim name after accepting Islam and a Nikah is performed using a non-Muslim name, the Nikah will still be valid.
