And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 And there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 and then created for them other vessels like those on which they ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 And they say: "When will this promise come to pass, if what you say is true?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 then they will not be able to make any testament, nor will they return to their people. 50
