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 has given you life, He will make you die and will make you live again. Surely the human being is ungrateful. 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 dispute with you, say: "Allah knows well what you do. 68 [For, indeed,] God will judge between you [all] on Resurrection Day with regard to all on which you were wont to differ. 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 Yet instead of God, they worship something for which God has sent no authority and about which they have no knowledge. The wrongdoers will have no helper. 71 And when Our clear communications are recited to them you will find denial on the faces of those who disbelieve; they almost spring upon those who recite to them Our communications. Say: Shall I inform you of what is worse than this? The fire; Allah has promised it to those who disbelieve; and how evil the resort! 72
