Remember when you killed a man and blamed each other for the deed, God brought to light what you concealed. 72 So We commanded, "Strike the corpse of the murdered man with a part of the sacrificed cow. See how Allah brings the dead to life and shows you His Signs, so that you may understand". 73 Yet, in spite of this, your hearts only hardened like rocks or even harder, but among rocks are those from which rivers flow; and there are also those which split open and water gushes forth; as well as those that roll down for fear of God. And God is not negligent of all that you do. 74 ۞ Do you then hope that they will believe in you when some of them have already heard the word of God and then, after having understood it, they knowingly perverted it? 75 For when they meet the faithful, they say: "We believe;" but when among themselves, they say: "Why do you tell them what the Lord has revealed to you? They will only dispute it in the presence of your Lord. Have you no sense indeed?" 76 Know they not that Allah knoweth that which they hide and that which they make known? 77 And there are among them unlettered people who have no real knowledge of the divine writ, [following] only wishful beliefs and depending on nothing but conjecture. 78 Woe to those who write the Book themselves and say, "This is from God," so that they may sell it for a small price! Woe unto them for what they have done and for what they have gained! 79 And they say: The Fire (of punishment) will not touch us save for a certain number of days. Say: Have ye received a covenant from Allah - truly Allah will not break His covenant - or tell ye concerning Allah that which ye know not? 80 Whoever earns evil and becomes engrossed in sin shall be doomed to Hell and abide therein for ever. 81 And (as for) those who believe and do good deeds, these are the dwellers of the garden; in it they shall abide. 82
