۞ 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 said: 'O Moses! I have indeed preferred you to all others by virtue of the Message I have entrusted to you and by virtue of My speaking to you. Hold fast therefore, to whatever I have granted you, and give thanks.' 144 We wrote advice and laws for him on Tablets about all kinds of things, saying, "Follow them and command your people to follow the good advice therein, and I will show you the dwellings of the evil-doers." 145 I will turn away from My communications those who are unjustly proud in the earth; and if they see every sign they will not believe in It; and if they see the way of rectitude they do not take It for a way, and if they see the way of error. they take it for a way; this is because they rejected Our communications and were heedless of 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
