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 gives you life, then makes you die; then He will bring you back to life again. Man is surely most ungrateful. 66 For every nation We have ordained religious ceremonies [e.g. slaughtering of the beast of cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of cattle which Allah kills by its natural death), but invite them to your Lord. Verily! You (O Muhammad SAW) indeed are on the (true) straight guidance. (i.e. the true religion of Islamic Monotheism). 67 If they do wrangle with thee, say, "Allah knows best what it is ye are doing." 68 "Allah will judge between you on the Day of Resurrection about that wherein you used to differ." 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 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 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
