Wherefore admonish thou! thou art not, by the grace of thy Lord, a soothsayer or a madman. 29 Or do they say: "[He is but] a poet - let us wait what time will do unto him"? 30 Say (unto them): Except (your fill)! Lo! I am with you among the expectant. 31 Does their reasoning prompt them to this, or they are a people rebellious? 32 What! They say, “He has invented the Qur'an”? Rather they do not have faith. 33 Let them then produce a recital like unto it (the Quran) if they are truthful. 34 Have they not been created by aught, or are they the creators? 35 Or did they create the heavens and the earth? Nay, but they are sure of nothing! 36 Do they own the treasures of your Lord? Have they any authority over God? 37 Or do they have a ladder (climbing which) they can hear (the secrets of heaven)? Let one who has heard then bring a clear proof. 38 Or has He daughters while you have sons? 39 Or is it that [they who reject thy message, O Muhammad, fear lest] thou ask of them a reward, so that they would be burdened with debt [if they should listen to thee]? 40 Or that the Unseen in it their hands, and they write it down? 41 Or do they want to entrap [thee in contradictions]? But they who are bent on denying the truth - it is they who are truly entrapped! 42 Or have they a god other than Allah? Exalted is Allah far above the things they associate with Him! 43 Even if they saw lumps falling from the sky they would say: 'A massed cloud' 44 So, leave them until they face their day (of doom) when they will be stunned. 45 the Day when none of their scheming will be of the least avail to them, and they will receive no succour. 46 And surely those who are unjust shall have a punishment besides that (in the world), but most of them do not know. 47 And so, await in patience thy Sustainer's judgment, for thou art well within Our sight. And extol thy Sustainer's limitless glory and praise whenever thou risest up, 48 And for part of the night also praise thou Him,- and at the retreat of the stars! 49
