He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you 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 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 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Have they not regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees everything. 19 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 20 Or who is he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness. 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the 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 God who has settled you on the earth and to Him you will be resurrected". 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say: The knowledge (thereof is only with Allah and I am only a plain warner. 26 So when they will see it close, the faces of the disbelievers will become ghastly, and it will be declared, “This is what you were demanding.” 27 Say (O dear Prophet Mohammed – peace and blessings be upon him), “What is your opinion –Allah may either destroy me and those with me, or have mercy on us – so who is such that will protect the disbelievers from the painful punishment?” 28 Say: "He is the Most Gracious: we have attained to faith in Him, and in Him have we placed our trust; and in time you will come to know which of us was lost in manifest error." 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
