(Muhammad), remind them, by the Grace of your Lord, that you are neither a soothsayer or an insane person. 29 Do they say: "He is a poet for whom we expect an adverse turn of fortune?" 30 Say: 'Await! I shall be awaiting with you.' 31 Is it that their faculties of understanding urge them to this, or are they but a people transgressing beyond bounds? 32 Do they say: “He has himself fabricated the Qur'an?” No; the truth is that they are altogether averse to believing. 33 Then let them produce speech the like thereof, if they are truthful. 34 Were they created out of nothing, or are they their own creators? 35 Or, did they create the heavens and the earth? No, their belief is not certain! 36 Or, are the treasures of your Lord in their keeping? Or, are they the controllers? 37 Or have they a stairway [into the heaven] upon which they listen? Then let their listener produce a clear authority. 38 Or has He only daughters and ye have sons? 39 Do you (Muhammad) ask them for any payment (for your preaching) which they cannot afford? 40 Or, is the Unseen in their keeping, so they are writing it down? 41 Do they want to hatch some plot? Those who deny the truth will be the victims of the plot. 42 Or have they a god other than Allah? Exalted is Allah far above the things they associate with Him! 43 And were they to see a portion of the sky falling, they will say, “It is a heap of clouds.” 44 Wherefore let them alone, till they meet their Day whereon they shall swoon. 45 A day in which their guile will naught avail them, nor will they be helped. 46 For the harmdoers there is indeed, a punishment before that, but most of them do not know. 47 So wait patiently for the Judgement of your Lord -- you are certainly under Our watchful eye. And glorify and celebrate the praises of your Lord when you rise up [from your sleep]. 48 Extol His glory at night, and at the setting of the stars. 49
