He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 15 Do you feel secure that He who is in heaven will not cause the earth to sink beneath you and then begin to quake? 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 verily those before them denied, then (see) the manner of My wrath (with them)! 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 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 (O Muhammad SAW): "Tell me! If Allah destroys me, and those with me, or He bestows His Mercy on us, - who can save the disbelievers from a painful torment?" 28 Say, "He is the Most Gracious: we believe in Him and we put our trust in Him. You will soon come to know who is in evident error." 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
