۞ And We treated with Musa thirty nights, and We completed them with ten; so the appointment of his Lord was completed by forty nights. And Musa said unto his brother Harun: act thou in my place among my people, and rectify, and follow not the way of the corrupters. 142 When Moses arrived at the appointed time and his Lord spoke to him, he said: "O Lord, reveal Yourself to me that I may behold You." "You cannot behold Me," He said. "But look at the mountain: If it remains firm in its place you may then behold Me." But when his Lord appeared on the mountain in His effulgence, it crumbled to a heap of dust, and Moses fell unconscious. When he came to, he said: "All glory to You. I turn to You in repentance, and I am the first to believe." 143 (Allah) said: "O Moses! I have chosen thee above (other) men, by the mission I (have given thee) and the words I (have spoken to thee): take then the (revelation) which I give thee, and be of those who give thanks." 144 And We wrote down on tablets admonitions and clear explanations of all things for Moses, and ordered him: "Hold fast to them, and command your people to observe the best in them. I will show you the abode of the wicked. 145 I shall turn away from My signs those who, without any right, behaved haughtily in the earth, even if they may witness each and every sign, they shall not believe therein. And even if they see the right path, they shall still not follow it; but if they see the path of error, they shall choose it for their path. This is because they rejected Our signs as false and were heedless to 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
