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 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 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 And assuredly those before them belied; then what wise hath been My wrath! 18 Have they not seen the birds above them spreading out their wings and closing them? Naught upholdeth them save the Beneficent. Lo! He is Seer of all things. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Who can provide for you, if He withholds His provision? Yet they obstinately persist in rebellion and avoidance of the truth. 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: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say: 'The knowledge is with God; I am only a clear 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 (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 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 [unto those who deny the truth]: "What do you think? If of a sudden all your water were to vanish underground, who [but God] could provide you with water from [new] unsullied springs?" 30
