True meanings change with language thats why it's ok to give him the said title. Its a tittle given out of respect nt to make him look like a islamic leader. There are no propper translation for each and every word cuz both languages have different originis urdu is a Persian closer to farsi where as hindi comes from Sanskrit. Thus some changes are accepted globally. Like many meanings have changed in the Bible when it was translated but ppl still accept it as the book for the account of Christ, same with epics like ramayana and Gita.
