And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Glory be to Him, Who has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, the All-Knowing; 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. 40 And a sign to them is that We bear their offspring in the laden ship. 41 and created for them similar things to ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 Unless by mercy from Us, and as a comfort for a while. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 Not a Sign comes to them from among the Signs of their Lord, but they turn away therefrom. 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 is this promise, if you should be truthful?" 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 then they will not be able to make any testament, nor will they return to their people. 50
