۞ And We made an appointment with Moses for thirty nights and perfected them by [the addition of] ten; so the term of his Lord was completed as forty nights. And Moses said to his brother Aaron, "Take my place among my people, do right [by them], and do not follow 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 He replied, "Moses, I have chosen you of all mankind for My messages and My Words. Hold fast to what I have given you, and be among 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 I shall turn from My signs those who wax proud in the earth unjustly; though they see every sign, they will not believe in it, and though they see the way of rectitude they will not take it for a way, and though they see the way of error, they will take it for a way. That, because they have cried lies to Our signs and heeded them not.' 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
