A Sign for them is the earth that is dead: We do give it life, and produce grain therefrom, of which ye do eat. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 Of the signs for them is how We separated the day from the night and thus they remained 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 determined it in phases till it returns like an old palmbranch. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 And We have created for them of the like thereunto, so on them they ride. 42 And if We will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 save as a mercy from Us, and enjoyment 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 and whenever a revelation out of their Lord's revelations comes to them, they ignore 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 threat come to pass, if you are 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 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
