It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 16 Do you feel secure that He Who is in the heaven will not let loose upon you a storm of stones? Then shall you know what My warning is like! 17 Those before them had also denied. And how was My punishment then! 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 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 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 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 scattered you in the earth, and unto Him you shall be mustered.' 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 26 When they will see it near at hand, the faces of all those who had denied it will be distraught, and then they will be told: “This is the doom which you used to ask for.” 27 Say: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers 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: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
