Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are 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 determined for it phases, until it returns [appearing] like the old 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 carried their offspring in the laden Ark (of Noah). 41 and then created for them other vessels like those on which they ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 Yet there never comes to them any sign of their Lord's signs, but they 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 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 And they will not be able to make a disposition, nor to their family they return. 50
