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 He it is Who gave you life, then He will cause you to die, and then will give you life (again). Lo! man is verily an ingrate. 66 For every people We have prescribed a way of worship which they follow. So, (O Muhammad), let them not dispute with you concerning this, and call them to Your Lord. You are certainly on the Straight Way. 67 And if they dispute with you, say: "Allah knows well what you do. 68 Allah will judge between you on the Day of Resurrection concerning that over which you used to differ." 69 Didst thou not know that God knows all that is in heaven and earth? Surely that is in a Book; surely that for God is an easy matter. 70 And yet they [who claim to believe in Him often] worship [other beings or forces] beside God - something for which He has never bestowed any warrant from on high, and [of the reality] whereof they cannot have any knowledge: and such evildoers shall have none to succour them [on Judgment Day]. 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
