And the majority of the human beings will not believe though you desire excessively.
Though Prophet Muhammed (PBH) did not ask for any reward for his preaching and though they see a number of proofs of the existence of Allah (SWT) and His powers, still the majority will not believe and will associate partners with Him.

Then do they feel secure from the covering of punishment of Allah which will come on them or the hour of doom which will come suddenly while they do not perceive ?
The punishment of Allah (SWT) or the end of the world will be brought about suddenly.

Say, “”This is my way, I invite towards Allah (being) on sure proof, myself and those who follow me. And Glory be to Allah and I am not of the polytheists.””
Prophet Muhammed (PBH) is asked to declare that he is not a polytheist and he invites only towards Allah (SWT).

And We did not send (any messenger) before you but they were men from among the people of the cities, to whom We had communicated. Have they not travelled in the earth and seen how the end of those before them was (brought about)? And the home of the hereafter is better for those who guard (against evil). Then do you not have sense?
Allah (SWT) had raised in every community men from among them as His messengers 16:36 who were helped by Him and those who denied were punished. In their histories there is a lesson for the learned. The Quran confirms the truth of the earlier Divine books, it explains everything concerned with us, it guides towards paradise and is thus a mercy for those who believe that it is a Divine revelation.
