Have you not seen that God, through His command, has made all that is in the earth and the ships that sail on the sea subservient to you? He prevents the sky from falling on the earth unless He decides otherwise. God is Compassionate and Merciful to mankind. 65 And it is He Who gave you life, then will cause you to die, and will then revive you; indeed man is very ungrateful. 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 And if they argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do. 68 [For, indeed,] God will judge between you [all] on Resurrection Day with regard to all on which you were wont to differ. 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, 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 revelations are recited unto them, thou knowest the denial in the faces of those who disbelieve; they all but attack those who recite Our revelations unto them. Say: Shall I proclaim unto you worse than that? The Fire! Allah hath promised it for those who disbelieve. A hapless journey's end! 72
