who am I?

[O, Messenger] When your God stated to the Angels "I will appoint a Divine Governor on The earth" they said "[O, our creator]Do you appoint the kind of creature who will make Mischief therein and will shed blood? While we repeat the Remembrance of thanksgiving due to your Absolute purity and we celebrate Your Holiness." Allah stated:" indeed I know what you don't know." Holy Quran [2; 30].
