The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We produce therein orchard with date-palms and vines, and We cause springs 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs on its fixed course for a term (appointed). That is the Decree of the All-Mighty, 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 allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming. 40 And a sign for them is that We carried their forefathers in a laden ship. 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 But (by) mercy from Us and for enjoyment till 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 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: “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 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50
