Have you not seen that God, through His command, has made all that is in the earth and the ships that sail on the sea subservient to you? He prevents the sky from falling on the earth unless He decides otherwise. God is Compassionate and Merciful to mankind. 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 And if they dispute with you, then say, "Allah is most knowing of what you do. 68 Allah will judge between you on the Day of Resurrection concerning what you dispute. 69 Did you not realise that Allah knows all that is in the heavens and in the earth? Indeed all this is in a Book; indeed this is easy for Allah. 70 And they worship besides Allah others for which He has sent down no authority, and of which they have no knowledge and for the Zalimun (wrong-doers, polytheists and disbelievers in the Oneness of Allah) there is no helper. 71 And when Our signs are recited to them, clear signs, thou recognisest in the faces of the unbelievers denial; wellnigh they rush upon those who recite to them Our signs. Say: 'Shall I tell you of something worse than that? The Fire -- God has promised it to the unbelievers -- an evil homecoming!' 72
