۞ And We appointed with Musa a time of thirty nights and completed them with ten (more), so the appointed time of his Lord was complete forty nights, and Musa said to his brother Haroun: Take my place among my people, and act well and do not follow the way of the mischief-makers. 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 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 From My signs I will turn away the unrightfully, arrogant in the land, so that even if they witness every sign they would not believe it. If they see the path of righteousness, they shall not take it as a path; but if they see the path of error, they shall take it for their path because they belied Our signs and were inattentive towards them. 146 Hence, all who give the lie to Our messages, and [thus] to the truth of the life to come - in vain shall be all their doings: [for] are they to be rewarded for aught but what they were wont to do? 147
