Do you not see that Allah has subjected to you all that is on the earth, and the ships which run upon the sea by His command? He holds the sky back lest it should fall upon the earth except by His permission. Allah is Gentle to people, the Most Merciful. 65 it is He who gave you life. Then He will cause you to die. Then He will give you life again. Surely, man is most ungrateful. 66 Unto every community We have appointed a rite which they perform. Let them not therefore contend with thee in the affair; and call them thou unto thy Lord, verily thou art on true guidance. 67 And if they should dispute with thee, do thou say, 'God knows very well what you are doing. 68 Allah will judge among you on the Day of Resurrection concerning matters about which you disagreed." 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 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 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
