It is He Who has made the earth manageable for you, so traverse ye through its tracts and enjoy of the Sustenance which He furnishes: but unto Him is the Resurrection. 15 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 16 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except (Allah) Most Gracious: Truly (Allah) Most Gracious: Truly it is He that watches over all things. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 20 Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]! 21 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 22 Say: 'It is He who produced you, and appointed for you hearing and sight and hearts; little thanks you show!' 23 Say: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 And they say, “When will this promise come, if you are truthful?” 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 But when they see it approaching, the faces of those who disbelieve will be distressed, and it will be said, "This is that for which you used to call." 27 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 28 Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
