Remember when you killed a man and blamed each other for the deed, God brought to light what you concealed. 72 We said: "Apply this [principle] to some of those [cases of unresolved murder]: in this way God saves lives from death and shows you His will, so that you might [learn to] use your reason." 73 Then your hearts became hardened thereafter and are like stones, or even yet harder; for there are stones from which rivers come gushing, and others split, so that water issues from them, and others crash down in the fear of God. And God is not heedless of the things you do. 74 ۞ O Muslims, do you then expect that these people will accept your invitation and become believers? whereas there have always been among them some who have been hearing the Word of God, understanding it well and then perverting and tampering with it knowingly. 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 Do they not know that God knows all that they conceal and all that they disclose? 77 And some of them are common (people) and do not know the Book, but only wishful thoughts, and they are only doubters. 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 will most certainly not touch us for more than a limited number of days." Say [unto them]: "Have you received a promise from God - for God never breaks His promise - or do you attribute to God something which you cannot know?" 80 Nay, but whosoever hath done evil and his sin surroundeth him; such are rightful owners of the Fire; they will abide therein. 81 but those who believe and do good works are the heirs of Paradise; there they shall abide forever. 82
