Therefore, remind and preach (mankind, O Muhammad SAW of Islamic Monotheism). By the Grace of Allah, you are neither a soothsayer, nor a madman. 29 Or do they say, 'He is a poet for whom we await Fate's uncertainty'? 30 Say: 'Wait if you will; I shall be waiting with you' 31 Do their minds command them to do this, or are they an outrageous folk? 32 What! They say, “He has invented the Qur'an”? Rather they do not have faith. 33 Then let them produce speech the like thereof, if they are truthful. 34 Or were they created of themselves? Or are they the creators? 35 Or have they created the heavens and the earth? In fact they are certain of nothing. 36 Or are with them the treasures of your Lord? Or are they the tyrants with the authority to do as they like? 37 Or have they a ladder, by which they can (climb up to heaven and) listen (to its secrets)? Then let (such a) listener of theirs produce a manifest proof. 38 Or, [if you believe in God, how can you believe that] He has [chosen to have] daughters, whereas you yourselves would have [only] sons? 39 Or askest thou a hire from them so that they are with debt laden? 40 Or [do they think] that the hidden reality [of all that exists] is almost within their grasp, so that [in time] they can write it down? 41 Or do they desire a war? But those who disbelieve shall be the vanquished ones in war. 42 Or have they a god other than Allah? Glory be to Allah from what they set up (with Him). 43 And were they to see a portion of the sky falling, they will say, “It is a heap of clouds.” 44 Then let them be (O Muhammad), till they meet their day, in which they will be thunder-stricken, 45 when their stratagem shall be of no avail to them, nor shall they be succoured. 46 And verily, for those who do wrong, there is a punishment beyond that. But most of them know not. 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 and also celebrate His praise at night, and at the retreat of the stars. 49
