Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Limitless in His glory is He who has created opposites in whatever the earth produces, and in men's own selves, and in that of which [as yet] they have no knowledge. 36 And there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, the All-Knowing; 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 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 how We carried them and their offspring inside the laden Ark 41 And have created for them of the like thereof whereon they ride. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed you are truthful.” 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 So they shall not be able to make a bequest, nor shall they return to their families. 50
