Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 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 Of the signs for them is how We separated the day from the night and thus they remained in darkness; 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, 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 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 lodged them in a laden ship, while they were in their forefathers backs. 41 and then created for them other vessels like those on which they ride. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 Never came a token of the tokens of their Lord to them, but they did turn away from it! 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 And they say, “When will this promise be fulfilled, if you are truthful?” 48 They do not await except one blast which will seize them while they are disputing. 49 Then they would not be able to make a will, or go back to their people. 50
