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 in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning. 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 19 Or, who is it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 20 Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]! 21 Who is better guided: he who walks grovelling on his face, or 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: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 27 SAY [O Prophet]: "What do you think? Whether God destroys me and those who follow me, or graces us with His mercy - is there anyone that could protect [you] deniers of the truth from grievous suffering [in the life to come]?" 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
