And you remember the occasion when your Lord said to the Angels: “Indeed, I am going to place a vicegerent on the earth”. They asked: “Are you placing therein one who will do mischief on it and will shed the blood while we are glorifying Your Praise and Sanctifying You?” He replied: “Indeed I know what you don’t know”.
Before mankind, the Sprites (Jinns) were created and deputed on earth as the vicegerents of the Lord. Mankind and Jinn are given the freedom to be grateful or ungrateful. Due to that, they are deputed as the vicegerents of the Lord. When all Sprites became transgressors on earth without bearing Lord’s representation, Angels under the leadership of Iblis wiped them out completely. At that time, Iblis who belonged to Jinn as mentioned in verse 18: 50 hadn’t turned into a rebel Satan. That is why Angels asked: “Are you placing therein one who will do mischief on it and will shed blood”. The nine hundred and ninety-nine out of thousand are the Arabic Quran reading Fujjar who are serving Satan and following his footsteps as explained in verses 2: 168-169. They are denoted as the worst among thousand communities of Lord’s creatures for not utilizing their intelligence as explained in verse 8: 22.
Mankind is deputed not only to glorify the Lord and to sanctify Him, but also to identify the Lord, identify and purify the soul, and to prepare the Paradise here utilizing the Light Adhikr. It is the responsibility of mankind bestowed with intelligence to produce food and maintain the sustenance for all the creatures belonging to thousand communities of the Lord, and thus to provide chances for them to pray and glorify Lord with their soul. But the only believer who is one in a thousand will testify Adhikr as the Food, Cloth, and Sight of the human soul and bear the representation of Lord. See explanation 2: 6-7, 24, and 6: 165.
