And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 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 [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 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 token unto them is that We bear their offspring in the laden ship, 41 And We made similar vessels for them to ride. 42 And if We should will, We could drown them; then no one responding to a cry would there be for them, nor would they be saved 43 Except as a mercy from Us and 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 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 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
