But [then] - how many a sign is there in the heavens and on earth which they pass by [unthinkingly,] and on which they turn their backs! 105 And most of them believe not in Allah except as they are associators. 106 Do they really believe that an all-embracing punishment of God will not come upon them, or the Day of Doom overtake them suddenly while they remain unaware? 107 Say, "This is my way; I invite to Allah with insight, I and those who follow me. And exalted is Allah; and I am not of those who associate others with Him." 108 All the messengers We sent before you [Muhammad] were human beings to whom We made revelations; they were men chosen from the people of their towns. Did they not travel across the earth and see the end of those before them? Those who are mindful of God prefer the life to come. Will you not then understand? 109 Till, when the Messengers despaired, deeming they were counted liars, Our help came to them and whosoever We willed was delivered. Our might will never be turned back from the people of the sinners. 110 In their stories there is a lesson for men of understanding. This [Quran] is no invented tale, but a confirmation of the previous [scripture] and a detailed explanation of all things as well as guidance and mercy to true believers. 111
