Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
Abdul Manaf means "servant of Manaf, " Manaf is the name of the pre-Islamic idol in Makkah. Also, the name Abdul 'Uzza which means "servant of 'Uzza," was also a name of an idol.
Therefore, it is necessary to change this name, even in documents etc.
This cannot be undone and I am sure it will be greatly appreciated.
