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, will cause you to die, and will again give you life: Truly man is a most ungrateful creature! 66 For every people We have prescribed a way of worship which they follow. So, (O Muhammad), let them not dispute with you concerning this, and call them to Your Lord. You are certainly on the Straight Way. 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 concerning that wherein ye used to differ. 69 Are you not aware that Allah knows all that is in the heaven and the earth? Surely it is all preserved in a Book. Indeed that is easy with Allah. 70 And they worship besides Allah that for which He has not sent down authority and that of which they have no knowledge. And there will not be for the wrongdoers any 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
