Q 2: Is it Sunnah (action following the teachings of the Prophet)
to change the person's name?
It is obligatory to change a name if it is prohibited to use it, such as names which describe their holders as being servants of others beside Allah (Exalted be He). If a name indicates foul words or meanings, it should be changed to a better one, according to the guidance of the Prophet (peace be upon him), as there are many proofs in the Sunnah supporting this.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
