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 And it is He Who gave you life, then will cause you to die, and will then revive you; indeed man is very 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 argue with you, say: 'Allah knows best all that you do. 68 On the Day of Resurrection, Allah will judge between you concerning that in which you vary. 69 Know you not that Allah knows all that is in heaven and on earth? Verily, it is (all) in the Book (Al-Lauh Al-Mahfuz). Verily! That is easy for Allah. 70 And they serve besides Allah that for which He has not sent any authority, and that of which they have no knowledge; and for the unjust 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
