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 gave you life, and then will cause you to die, and will again give you life (on the Day of Resurrection). Verily! Man is indeed an ingrate. 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 Allah will judge between you on the Day of Resurrection concerning that over which you used to differ." 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 worship, beside Allah, that for which He hath revealed no authority and that whereof they have no knowledge; and for the wrong-doers there shall not be a helper. 71 And when Our clear communications are recited to them you will find denial on the faces of those who disbelieve; they almost spring upon those who recite to them Our communications. Say: Shall I inform you of what is worse than this? The fire; Allah has promised it to those who disbelieve; and how evil the resort! 72
