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 To every nation We appointed acts of devotion which they observe, therefore they should not dispute with you about the matter and call to your Lord; most surely you are on a right way. 67 And if they [try to] argue with thee, say [only]: "God knows best what you are doing." 68 God will judge between you on the Day of Judgement in what you are at variance." 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 Yet they worship, besides Allah, things for which no authority has been sent down to them, and of which they have (really) no knowledge: for those that do wrong there is no helper. 71 As it is, whenever Our messages are conveyed unto them in all their clarity, thou canst perceive utter repugnance on the faces of those who are bent on denying the truth: they would almost assault those who convey Our messages unto them! Say: "Shall I, then, tell you of something worse than what you feel at present? It is the fire [of the hereafter] that God has promised to those who are bent on denying the truth: and how vile a journey's end!" 72
