He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 15 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 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 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 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 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter 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 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 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, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 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: "He is (Allah) Most Gracious: We have believed in Him, and on Him have we put our trust: So, soon will ye know which (of us) it is that is in manifest error." 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
