“And [mention, O Muhammad], when your Lord said to the angels, “Indeed, I will make upon the earth a successive authority.” They said, “Will You place upon it one who causes corruption therein and sheds blood, while we declare Your praise and sanctify You?” Allah said, “Indeed, I know that which you do not know.” (Qur’an 2 :30)
Vicegerent i.e “Khalifa” is the one who exercises the duty assigned to him by his Lord as per his capacity and Hence, whatever authority he possesses is not inherently his own but granted by the creator. Certainly man has been given more liberal power, but still he has been confined within certain limits. He has been authorised to carry out His plan not what he desires.. We see in the world if any company is authorised so he should follow the lay out of that company that’s his duty so in the same way we are representatives of Allah on earth. Thus, he is not entitled to do what he pleases, but is obliged to carry out the will of His master. For that he must follow His guidance and plan. That can guarantee success and peace. Man is charged with the power of mind sense, reason, and intellect to accomplish His task.
The verse explains that it is honoured for the man to be appointed as a vicegerent on earth to implement his law and glorify His praise. Instead of following owner’s plan he starts thinking that he himself is the real owner of authority delegated to him in whatever manner he is pleased, or acknowledge someone other than the real owner as his Lord and master and to follow his directions, these would be deemed acts of infidelity and rebellion. Obviously, the whole mankind is the vicegerent of Allah and not only the selected numbers of people. However, there is no doubt that some selected individuals among human being might be perfect vicegerents of Allah due to their proximity to Him and compliance with law. In view of the above discussions Allah all-knowing and all-wise concluded that weak human in all species can conquer the world with his amazing intelligent if he surrendered himself to His will.
