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 And yet, after all this, your hearts hardened and became like rocks, or even harder: for, behold, there are rocks from which streams gush forth; and behold, there are some from which, when they are cleft, water issues; and behold, there are some that fall down for awe of God. And God is not unmindful of what 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 those who have attained to faith, they say: "We believe [as you believe]" - but when they find themselves alone with one another, they say: "Do you inform them of what God has disclosed to you, so that they might use it in argument against you, quoting the words of your Sustainer? Will you not, then, use your reason?" 76 Do they not know that Allah knows all whatever they hide and whatever they disclose? 77 Then there are among them some un-lettered people who have no knowledge of the Book but depend upon empty hopes and are guided by mere conjecture and guess-work. 78 So woe to their learned people, who write the law with their own hands and then say to the people, "This is from Allah," so that they might gain some paltry worldly end. (They do not see that) this writing of their hands will bring woe to them and what they gain thereby will lead to their ruin. 79 And they say: "The Fire shall not touch us but for a few numbered days:" Say: "Have ye taken a promise from Allah, for He never breaks His promise? or is it that ye say of Allah what ye do not know?" 80 Yes, why not?* The one who earns evil and his sin surrounds him; he is from the people of fire (hell); they will remain in it forever. (You will remain in the fire forever). 81 And (as for) those who believe and do good deeds, these are the dwellers of the garden; in it they shall abide. 82
