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 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 Unto every community We have appointed a rite which they perform. Let them not therefore contend with thee in the affair; and call them thou unto thy Lord, verily thou art on true guidance. 67 And if they dispute with thee, say thou: Allah knoweth best that which ye work. 68 He will issue His decree about your differences on the Day of Judgment." 69 Knowest thou not that Allah knoweth whatsoever is in the heaven and the earth? Verily that is in a Book; verily that is for Allah easy. 70 Yet instead of God, they worship something for which God has sent no authority and about which they have no knowledge. The wrongdoers will have no helper. 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
