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 And He it is Who gave you life, then He will cause you to die, and then will give you life (again). Lo! man is verily an ingrate. 66 We have determined for each community a way of worship which they follow. So they should not contend with you in this matter; and you should go on calling them to your Lord. You are surely on the right path. 67 And if they argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do. 68 God will judge between you on the Day of Judgement in what you are at variance." 69 Know you not that Allah knows all that is in heaven and on earth? Verily, it is (all) in the Book (Al-Lauh Al-Mahfuz). Verily! That is easy for Allah. 70 And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper. 71 When Our authoritative revelations are recited to the unbelievers, you can clearly read the dislike on their faces. They almost attack those who read Our revelations to them. Say to them, "Should I tell you about what is the worst thing for you than these revelations? It is the fire which God has prepared for the unbelievers. What a terrible destination! 72
