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 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 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 argue with you (as regards the slaughtering of the sacrifices), say; "Allah knows best of what you do. 68 Allah will judge between you on the Day of Resurrection concerning what you dispute. 69 Hast thou not known that Allah knoweth all that is in the heaven and the earth? Lo! it is in a record. Lo! that is easy for Allah. 70 And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper. 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
