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 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 Unto each nation have We given sacred rites which they are to perform; so let them not dispute with thee of the matter, but summon thou unto thy Lord. Lo! thou indeed followest right guidance. 67 if they should dispute with you, then say, "God is well aware of what you do." 68 "Allah will judge between you on the Day of Judgment concerning the matters in which ye differ." 69 Dost thou not know that God knows all that occurs in heaven as well as on earth? All this, behold, is in [God's] record: verily, [to know] all this is easy for God. 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 As it is, whenever Our messages are conveyed unto them in all their clarity, thou canst perceive utter repugnance on the faces of those who are bent on denying the truth: they would almost assault those who convey Our messages unto them! Say: "Shall I, then, tell you of something worse than what you feel at present? It is the fire [of the hereafter] that God has promised to those who are bent on denying the truth: and how vile a journey's end!" 72
