It is He Who subjected the earth for you, therefore tread its paths and eat from Allah’s sustenance; and towards Him is the resurrection. 15 Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)? 16 Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a violent whirlwind? Then you shall know how (terrible) has been My Warning? 17 And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees 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 who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 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 has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 When they will see it near at hand, the faces of all those who had denied it will be distraught, and then they will be told: “This is the doom which you used to ask for.” 27 Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment? 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, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
