A Sign for them is the earth that is dead: We do give it life, and produce grain therefrom, of which ye do 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 its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what they do not know. 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, 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 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And have created for them of the like thereof whereon they ride. 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 it is said to them: "Beware of what is before you and what is past, that you may be treated with kindness;" 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
