The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 We have placed in it gardens of date palms and vines, and caused springs to gush [forth] from it, 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 has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 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 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 and then created for them other vessels like those on which they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 except through Our Mercy and as enjoyment for awhile. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 45 and no message of their Sustainer's messages ever reaches them without their turning 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 also say, 'When shall this promise come to pass, if you speak truly?' 48 They await but one Shout, which will surprise them while they are disputing. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
