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 We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! So will they not be grateful? 35 Exaltations to Him who created pairs of all the things the earth produces and of themselves, and that of which they have no knowledge. 36 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged 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 measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. 40 And a sign to them is that We bear their offspring in the laden ship. 41 And We have created for them similar (vessels) on which they ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 Unless it be a mercy from Us, and as an enjoyment for a while. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 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 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
