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 And He is the one who gave you life; then He causes you to die and then will [again] give you life. Indeed, mankind is ungrateful. 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 God shall judge between you on the Day of Resurrection touching that whereon you were at variance.' 69 Did you not realise that Allah knows all that is in the heavens and in the earth? Indeed all this is in a Book; indeed this is easy for Allah. 70 Yet they worship that for which He did not send down authority, and that of which they have no knowledge. Indeed, the harmdoers shall have no helpers. 71 And when Our signs are recited to them, clear signs, thou recognisest in the faces of the unbelievers denial; wellnigh they rush upon those who recite to them Our signs. Say: 'Shall I tell you of something worse than that? The Fire -- God has promised it to the unbelievers -- an evil homecoming!' 72
