Have you not seen that God, through His command, has made all that is in the earth and the ships that sail on the sea subservient to you? He prevents the sky from falling on the earth unless He decides otherwise. God is Compassionate and Merciful to mankind. 65 It is He who has given you life, He will make you die and will make you live again. Surely the human being is ungrateful. 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 what you dispute. 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 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 When Our Signs are plainly recited to them, you will perceive utter repugnance on their faces and it all but seems as if they will soon pounce upon those who recite Our Signs to them. Say: "Shall I tell you what is worse than that? The Fire with which Allah has threatened those who disbelieve. That is truly an evil end." 72
