۞ And when We did appoint for Moses thirty nights (of solitude), and added to them ten, and he completed the whole time appointed by his Lord of forty nights; and Moses said unto his brother, Aaron: Take my place among the people. Do right, and follow not the way of 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 He said: O Musa! surely I have chosen you above the people with My messages and with My words, therefore take hold of what I give to you and be of the grateful ones. 144 And We ordained for him in the tablets [of the Law] all manner of admonition, clearly spelling out everything. And [We said:] "Hold fast unto them with [all thy] strength, and bid thy people to hold fast to their most goodly rules." I will show you the way the iniquitous shall go. 145 I shall turn away from My revelations those who magnify themselves wrongfully in the earth, and if they see each token believe it not, and if they see the way of righteousness choose it nor for (their) way, and if they see the way of error choose if for (their) way. That is because they deny Our revelations and are used to disregard 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
