(Muhammad), remind them, by the Grace of your Lord, that you are neither a soothsayer or an insane person. 29 Or say they: (he is) a poet, (one) for whom we may expect the accident of time? 30 Say, "Wait, for indeed I am, with you, among the waiters." 31 Is it that their faculties of understanding urge them to this, or are they but a people transgressing beyond bounds? 32 Or say they: He hath invented it? Nay, but they will not believe! 33 Let them then produce a recital like unto it,- If (it be) they speak the truth! 34 Or were they created out of naught? Or are they the creators? 35 Or did they create the heavens and the earth? Nay, but they are sure of nothing! 36 Or do they have your Lord's treasures in their keeping? Or have absolute authority over them? 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 do they have knowledge of the Unknown which they write down? 41 Or do they desire a war? But those who disbelieve shall be the vanquished ones in war. 42 Or do they have a God besides Allah? Purity is to Allah from their ascribing of partners to Him. 43 If they should see a part of the heavens falling down, they would say, "A mass of clouds," 44 So leave them alone till they meet their Day, in which they will sink into a fainting (with horror). 45 The Day when their guile shall not relieve them a thing, and they shall not be helped. 46 And indeed, for those who have wronged is a punishment before that, but most of them do not know. 47 And wait thou patiently the judgment of thy Lord; verily thou art before Our eyes; and hallow the praise of thy Lord when thou uprisest. 48 and extol His glory at night, and at the time when the stars retreat. 49
