Do you not see God has harnessed all that is in the earth, to your service? And the boats ply in the ocean by His command. He holds the sky in position lest it should fall upon the earth save by His dispensation. Verily God is compassionate and kind to men. 65 It is He who revives you, then He will cause you to die and then He revives you. Indeed, the human is ungrateful. 66 Unto each nation have We given sacred rites which they are to perform; so let them not dispute with thee of the matter, but summon thou unto thy Lord. Lo! thou indeed followest right guidance. 67 If they do wrangle with thee, say, "Allah knows best what it is ye are doing." 68 He will issue His decree about your differences on the Day of Judgment." 69 Are you not aware that Allah knows all that is in the heaven and the earth? Surely it is all preserved in a Book. Indeed that is easy with Allah. 70 And they worship, beside Allah, that for which He hath revealed no authority and that whereof they have no knowledge; and for the wrong-doers there shall not be a helper. 71 When Our clear messages are read out to them you can see denial on the faces of unbelievers. They can hardly restrain themselves from attacking those who recite Our revelations. Tell them: "Should I give you news of something worse than this?" -- Hell, which God has promised the infidels. How evil a destination! 72
