There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Exaltations to Him who created pairs of all the things the earth produces and of themselves, and that of which they have no knowledge. 36 And a sign for them is the night; We strip it of the day and lo, they are in darkness. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 And We have created for them of the like thereunto, so on them they ride. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 It is only by Our mercy that they are granted provision for a time. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 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 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed you are truthful.” 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 And they will not be able to make a disposition, nor to their family they return. 50
