The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 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 for them is the night. We remove from it [the light of] day, so they are [left] 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 We have appointed positions for the moon till it returns like an old branch of the date palm. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 how We carried them and their offspring inside the laden Ark 41 and then created for them other vessels like those on which they ride. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 But (by) mercy from Us and for enjoyment till a time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 45 And never came an Ayah from among the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of their Lord to them, but they did turn away from it. 46 And when it is said to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
