It is He who has made the earth submissive to you. Walk about in its land and eat of His provision. To Him is the Resurrection. 15 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 16 Do you feel secure that He Who is in the heaven will not let loose upon you a storm of stones? Then shall you know what My warning is like! 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 19 What other army do you have to help you apart from Ar-Rahman?

Nay, but they are set in pride and frowardness. 21 Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? 22 (Muhammad), say, "It is God who has brought you into being and made ears, eyes, and hearts for you, but you give very little thanks". 23 Say: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say: The knowledge (thereof is only with Allah and I am only a plain warner. 26 So when they will see it close, the faces of the disbelievers will become ghastly, and it will be declared, “This is what you were demanding.” 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 28 Say: He is the Beneficent. In Him we believe and in Him we put our trust. And ye will soon know who it is that is in error manifest. 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
