۞ We appointed for Moses thirty nights, and completed (the period) with ten (more): thus was completed the term (of communion) with his Lord, forty nights. And Moses had charged his brother Aaron (before he went up): "Act for me amongst my people: Do right, and follow not the way of those who do mischief." 142 And when Moses came [to Mount Sinai] at the time set by Us, and his Sustainer spoke unto him, he said: "O my Sustainer! Show [Thyself] unto me, so that I might behold Thee!" Said [God]: "Never canst thou see Me. However, behold this mountain: if it remains firm in its place, then - only then - wilt thou see Me. And as soon as his Sustainer revealed His glory to the mountain, He caused it to crumble to dust; and Moses fell down in a swoon. And when he came to himself, he said: "Limitless art Thou in Thy glory! Unto Thee do I turn in repentance; and I shall [always] be the first to believe in Thee!" 143 (Allah) said: "O Musa (Moses) I have chosen you above men by My Messages, and by My speaking (to you). So hold that which I have given you and be of the grateful." 144 And We wrote for him, upon the tablets, the lesson to be drawn from all things and the explanation of all things, then (bade him): Hold it fast; and command thy people (saying): Take the better (course made clear) therein. I shall show thee the abode of evil-livers. 145 “And I shall turn away from My signs the people who unjustly wish to be admired in the earth; and if they see all the signs, they would not believe them; and if they see the path of guidance, they would not prefer to tread it; and if they see the way of error, they would present themselves to tread it; that is because they denied Our signs and were ignoring them. 146 Those who cry lies to Our signs, and the encounter in the world to come -- their works have failed; shall they be recompensed, except according to the things they have done? 147
