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 shall make you dead, then He shall give you life. Surely man 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 God will judge between you on the Day of Judgement in what you are at variance." 69 Are you not aware that Allah has knowledge of what is in the heaven and earth? This is (recorded) in a Book. That is easy for 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 Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieve, and worst indeed is that destination!" 72
