And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 so that they may eat of the fruit thereof, though it was not their hands that made it. Will they not, then, be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 We have ordained phases for the moon until finally it becomes like an old date-stalk. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 Unless by mercy from Us and as comfort for a while. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 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: “Spend (in the Way of Allah) out of the sustenance that Allah has provided you,” the unbelievers say to the believers: “Shall we feed him whom, Allah would have fed, had He so wished?” Say: “You are in evident error.” 47 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 They will have no time to make a will, nor shall they return to their own people. 50
