My name is Abde Nabi (slave of the Prophet). Some people told me that I had to change my name.

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

It is unlawful to be named Abd al-Nabi (slave of the Prophet (Sallallahu Alaihi wa Sallam) or to carry any similar names that include enslavement to anyone other than Allah - The Almighty. In addition, this name gives to the Prophet (Sallallahu Alaihi wa Sallam) an attribute that is peculiar to Allah, i.e. enslavement of people.
So, you should change this name.
Allah knows best.
