There is much evidence (of the existence of God) in the heavens and the earth which they see, but ignore. 105 Not only do they not believe in God, but also associate others with Him. 106 Do they, then, feel secure that an overwhelming chastisement shall not visit them, and the Hour shall not suddenly come upon them without their even perceiving it? 107 Say (O Muhammad SAW): "This is my way; I invite unto Allah (i.e. to the Oneness of Allah - Islamic Monotheism) with sure knowledge, I and whosoever follows me (also must invite others to Allah i.e. to the Oneness of Allah - Islamic Monotheism) with sure knowledge. And Glorified and Exalted be Allah (above all that they associate as partners with Him). And I am not of the Mushrikun (polytheists, pagans, idolaters and disbelievers in the Oneness of Allah; those who worship others along with Allah or set up rivals or partners to Allah)." 108 And We sent not before you [as messengers] except men to whom We revealed from among the people of cities. So have they not traveled through the earth and observed how was the end of those before them? And the home of the Hereafter is best for those who fear Allah; then will you not reason? 109 When at last the Messengers lost all hope of achieving success in their task and thought that everyone had called them liars, We gave them victory and saved whomever We chose to save. The guilty ones can not escape Our wrath. 110 Indeed, in the stories of these men there is a lesson for those who are endowed with insight. [As for this revelation,] it could not possibly be a discourse invented [by man]: nay indeed, it is [a divine writ] confirming the truth of whatever there still remains [of earlier revelations,] clearly spelling out everything, and [offering] guidance and grace unto people who will believe. 111
