It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 15 Are you so unafraid that He who is in Heaven will not open up the earth to swallow you, when it will begin to tremble? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly 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 who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 What, is he who walks, falling upon his face, more 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 is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say (O Muhammad SAW): "The knowledge (of its exact time) is with Allah only, and I am only a plain warner." 26 But when they see it drawing near, the faces of those who deny the truth will turn gloomy and they will be told, "This is what you were calling for." 27 Say: "Just think: If God destroys me and those with me, or is benevolent to us, who will then protect the unbelievers from a painful doom?" 28 Say thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 29 Say, "Have you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
