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 seeing that it is He who gave you life, and then will cause you to die, and then will bring you back to life: [but,] verily, bereft of all gratitude is man! 66 To every People have We appointed rites and ceremonies which they must follow: let them not then dispute with thee on the matter, but do thou invite (them) to thy Lord: for thou art assuredly on the Right Way. 67 And if they [try to] argue with thee, say [only]: "God knows best what you are doing." 68 Allah will judge between you on the Day of Resurrection concerning that over which you used to differ." 69 Do you not know that Allah knows what is in the heaven and the earth? Surely this is in a book; surely this is easy to Allah. 70 Yet they worship, besides Allah, things for which no authority has been sent down to them, and of which they have (really) no knowledge: for those that do wrong there is no 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
