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 For every people We have prescribed a way of worship which they follow. So, (O Muhammad), let them not dispute with you concerning this, and call them to Your Lord. You are certainly on the Straight Way. 67 And if they dispute with you, then say, "Allah is most knowing of what you do. 68 Allah will judge among you on the Day of Resurrection concerning matters about which you disagreed." 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 They serve, apart from God, that whereon He has sent down never authority and that whereof they have no knowledge; and for the evildoers there shall be 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
