And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 We have placed in it gardens of date palms and vines, and caused springs to gush [forth] from it, 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give thanks? 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 unto them is the night. We draw off the day therefrom, and lo! they are darkened. 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 the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 And We made similar vessels for them to 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 by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error. 47 And they say: "When will this promise (i.e. Resurrection) 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 So they shall not be able to make a bequest, nor shall they return to their families. 50
