He it is Who has subdued the earth to you. So walk about on its chest and eat of God's provisions.23 To Him you shall return on Resurrection.24 Do you feel secure that He Who is in the heaven25 would not cause you to sink underground, and the earth may start rocking suddenly? Do you feel secure that He Who is in the heaven would not send a whirlwind charged with stones on you?26 Then you shall know how terrible was My warning!27 And those who have gone before them also belied. Then see how severe was My chastisement!28 Do they not see the birds above them, spreading their wings and closing them? None is upholding them but the Mercifu1.29 He it is Who watches over everything.30 Tell, what army is there with you that can help you against the Merciful.31 The fact is that the disbelievers are lost in utter delusion. Or tell, who is there to provide for you if the Merciful should withhold His provision? In fact, these people persist in rebellion and aversion from the Truth. Just consider. Is he who is walking prone on his face32 better guided or he who is walking upright on a smooth road? Say to them, "Allah it is Who created you, and gave you the faculties of hearing and sight and gave you the hearts to think and understand, but you are seldom grateful."33 Say to them: Allah it is Who has dispersed you in the earth, and to Him you shall be gathered together.34 They say, "When will this promise be fulfilled if what you say be true?"35 Say, "The knowledge of it is with Allah, I am only a plain warner."36 Then, when they see it close at hand, the faces of all those who disbelieve, shall be distorted,37 and at that time it will be said to them, "This is the same that you were calling for." Say to them, "Have you ever considered that even if Allah should destroy me and those with me, or should bestow mercy upon us, who will save the disbelievers from the painful torment?"38 Say to them, "He is the All-Merciful. In Him we have believed and in Him have we put our trust.39 Soon you will know who is involved in grave error." Say to them, "Have you ever considered that if the water of your wells should sink down into the earth, who would then restore to you the running springs of water?"40
