The verse which is composed in the form of question and answer, tries to remind the polytheists of their mistakes and wrong judgement. Here the prophet is told to ask them;
``Who is the cherisher Lord of the heavens and the earth?'' And the prophet is not to wait for the idolaters to answer that question, that the answer is clear and easy, that there is no Creator other than Allah.
Then through a parable the believers and the unbelievers are compared. The faithful is likened to light and a man who can see, and the faithless to darkness and a man who is blind.
The verse also implies that Lordship is connected with being worshipped. It is not so that God may create something and then sit aside, leaving the creature alone and unattended. God's bestow of existence is ever continuous, and every creature gets existence from God's Sacred Essence newly and instant by instant.
