Therefore proclaim thou the praises (of thy Lord): for by the Grace of thy Lord, thou art no (vulgar) soothsayer, nor art thou one possessed. 29 Do they say: "He is a poet for whom we expect an adverse turn of fortune?" 30 Say thou: wait verily I am, with you, among the waiters. 31 is it their minds that prompt them [to say] this, or are they merely insolent people? 32 Or do they say: "He has fabricated it?" In fact, they will never believe. 33 Then let them bring an announcement like it if they are truthful. 34 Have they not been created from some source, or are they themselves the creators? 35 Or, did they create the heavens and the earth? No, their belief is not certain! 36 Or are thy Lord's treasuries in their keeping? Or are they the registrars? 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 daughters, and they 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 Ghaib (unseen) is with them, and they write it down? 41 Or are they contriving a stratagem against you? If so, that stratagem will rebound against the unbelievers. 42 Or have they a god other than Allah? Glory be to Allah from what they set up (with Him). 43 And if they should see a portion of the heaven coming down, they would say: Piled up clouds. 44 So leave them till they encounter their Day in which they shall be thunderstruck. 45 when their stratagem shall be of no avail to them, nor shall they be succoured. 46 Surely there are other torments besides this for those who are wicked, though 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 And proclaim His Purity during the night, and when the stars turn back. 49
