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 gave you life, will cause you to die, and will again give you life: Truly man is a most ungrateful creature! 66 For every religion We have appointed rites which they perform. So, [O Muhammad], let the disbelievers not contend with you over the matter but invite them to your Lord. Indeed, you are upon straight guidance. 67 And if they argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do. 68 On the Day of Resurrection, Allah will judge between you concerning that in which you vary. 69 Knowest thou not that Allah knoweth whatsoever is in the heaven and the earth? Verily that is in a Book; verily that is for Allah easy. 70 They worship things instead of God that have received no authority (from the heavens) nor have they any knowledge of such authority. The unjust people will have no one to help them. 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
