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 is in the heaven will not cause the earth to swallow you up while it shakes? 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 have gone before you also belied (their Messengers) then how was My disapproval! 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Who is there to give you food in case He withholds His bounty? Yet they persist in rebellion and aversion. 21 Is he who walks without seeing on his face, more rightly guided, or he who (sees and) walks on a Straight Way (i.e. Islamic Monotheism). 22 Say: “He it is Who has brought you into being, and has given you hearing and sight, and has given you hearts to think and understand. How seldom do you give thanks!” 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked for." 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 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 to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
