۞ We appointed for Moses thirty nights, and completed (the period) with ten (more): thus was completed the term (of communion) with his Lord, forty nights. And Moses had charged his brother Aaron (before he went up): "Act for me amongst my people: Do right, and follow not the way of those who do mischief." 142 And when Moses came [to Mount Sinai] at the time set by Us, and his Sustainer spoke unto him, he said: "O my Sustainer! Show [Thyself] unto me, so that I might behold Thee!" Said [God]: "Never canst thou see Me. However, behold this mountain: if it remains firm in its place, then - only then - wilt thou see Me. And as soon as his Sustainer revealed His glory to the mountain, He caused it to crumble to dust; and Moses fell down in a swoon. And when he came to himself, he said: "Limitless art Thou in Thy glory! Unto Thee do I turn in repentance; and I shall [always] be the first to believe in Thee!" 143 He said: 'Moses, I have chosen you from all mankind with My Messages and My Words. Therefore, take what I have given you, and be among the thankful.' 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 will turn away from My signs all those who are arrogant in the land without any right, so that even if they see all the signs they will not believe in them. If they see the right path, they shall not walk upon it: but if they see the path of error, they shall choose it for their path, because they have given the lie to Our signs and paid no heed to 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
