۞ Had God hastened the punishment of men as He hastens the good, the end of their term of life would already have been reached. We leave those who do not hope to meet Us groping along in their arrogance. 11 When trouble toucheth a man, He crieth unto Us (in all postures)- lying down on his side, or sitting, or standing. But when We have solved his trouble, he passeth on his way as if he had never cried to Us for a trouble that touched him! thus do the deeds of transgressors seem fair in their eyes! 12 And indeed We destroyed several generations before you when they crossed the limits – and their respective Noble Messengers came to them with clear proofs, but they were not such as would believe; this is how We reward the guilty. 13 Then We made you their successors in the land, so that We might observe how you would conduct yourselves. 14 Whenever Our authoritative revelations are recited to those who do not wish to meet Us in the life hereafter, say, "Bring us another book besides this one or change it." (Muhammad), tell them, "I can not change it myself. I only follow what is revealed to me. I fear that for disobeying my Lord I shall be punished on the great (Day of Judgment). 15 Say: "Had God willed it [otherwise,] I would not have conveyed this [divine writ] unto you, nor would He have brought it to your knowledge. Indeed a whole lifetime have I dwelt among you ere this [revelation came unto me]: will you not, then, use your reason?" 16 Who is then more unjust than who forges a lie against Allah or (who) gives the lie to His communications? Surely the guilty shall not be successful. 17 And they worship besides Allah things that hurt them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted be He above all that which they associate as partners with Him! 18 Mankind was but one nation, but differed (later). Had it not been for a word that went forth before from thy Lord, their differences would have been settled between them. 19 They say, 'Why has a sign not been sent down upon him from his Lord?' Say: 'The Unseen belongs only to God. Then watch and wait; I shall be with you watching and waiting.' 20
