After i reverted to islam i kept my name as Nuh Abdul Nasir. Is this permissible? As Al-Nasir is not from the 99 names of Allah.

Imam Ibn Baz said leaving this name is better, because an-Nasir is not established in the authentic narrations as a name of Allah, while an-Naseer is, and he pointed to Abd an-Naseer or Abd al-Malik instead. The Permanent Committee was stricter and said it is not permitted, since abd is only joined to a name that is established for Allah.
