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 is the one who gave you life; then He causes you to die and then will [again] give you life. Indeed, mankind is ungrateful. 66 To every People have We appointed rites and ceremonies which they must follow: let them not then dispute with thee on the matter, but do thou invite (them) to thy Lord: for thou art assuredly on the Right Way. 67 And if they argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do. 68 Allah will judge among you on the Day of Resurrection concerning matters about which you disagreed." 69 Didst thou not know that God knows all that is in heaven and earth? Surely that is in a Book; surely that for God is an easy matter. 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 Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieve, and worst indeed is that destination!" 72
