H.M. Ha-Meem (Hakeem the Wise, Majeed the Glorious, states that),

The revelation of this Book is from God, the Almighty, the Wise.

We have not created the heavens and earth and all that is between them but for a specific purpose, and for a term appointed. And yet, those who are determined to deny the truth turn away from what they are warned against. [Bil-Haqq = In Truth = For a specific purpose = With a definite Plan]

Say, 'Have you ever given thought to what it is that you call upon instead of God? Show me what they have created of the earth. Or do they have a share in the heavens? Bring me (authority) from even a previous scripture, or even some remains of knowledge if you are truthful.'

And who could be further astray than one who invokes, instead of God, such as do not respond to him even until the Day of Resurrection, and, in fact, are totally unaware of their call.

And when mankind are gathered together, the false deities will become enemies to those who worshiped them, and will utterly reject their worship.

But when Our clear messages are conveyed to them, the rejecters say of the truth as soon as it reaches them, 'This is obviously a magical lie.' [Sihr = Magic = Lie = Delusion = Spellbinding eloquence = Amazing = Incredible]

Or do they say, 'He has invented all this?' Say, 'If I have invented it, still you have no power to support me against God. He is fully Aware of your reckless flight of imagination. He suffices as a Witness between me and you. And He is the Forgiving, the Merciful.' [You shall come to know what you now do not. And the Forgiving, the Merciful God has ordained the Law of Respite for you 37:175, 39:39]

Say, 'I am not the first of the Messengers, nor do I know what will be done with me or with you. I do but follow what is revealed to me, and I am but a plain warner.'

Say, 'What if it is from God and you rejected it! A witness from the Children of Israel has already borne witness to the advent of one like himself. And he has believed while you are showing arrogance. God does not guide people who relegate the truth.' [A witness from the Children of Israel = Moses, in Deuteronomy xviii, 15-18, 'A Prophet like unto me.' Some commentators mention a hadith referring to Hazrat Abdullah bin Salam, a convert from Judaism, as being the witness. But that proposition is obviously too weak to find a place in the Qur'an]
