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 It is He Who gave you life, will cause you to die, and will again give you life: Truly man is a most ungrateful creature! 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 If they argue with you, say: 'Allah knows best all that you do. 68 He will issue His decree about your differences on the Day of Judgment." 69 Do you not know that Allah knows what is in the heaven and the earth? Surely this is in a book; surely this is easy to 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 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
