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 you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Or can you ever feel secure that He who is in heaven will not let loose against you a deadly stormwind, whereupon you would come to know how [true] My warning was? 17 And certainly those before them rejected (the truth), then how was My disapproval. 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 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 Say: 'It is He who has created you and given to you hearing, sight and hearts but little is it that you thank' 23 Say: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 They say, "When will this torment take place if what you say is true?" 25 Say: The knowledge is with Allah only, and I am but 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 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?" 30
