۞ 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 Musa came at Our appointment, and his Lord spake unto him, he said my Lord! shew Thyself unto me, that I may look at Thee! He said: thou canst not see Me: but look at the yonder mount; if it stands in its place, then thou wilt see Me. Then when his Lord unveiled His glory unto the mount, it turned it to dust, and Musa fell down thunderstruck. Then when he recovered, he said: hallowed be Thou! I turn unto Thee repentant, and I am the first of the believers, 143 He said: O Musa! verily I have chosen thee above mankind by My messages and by My speaking; so hold fast thou that which I have given thee, and be of 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 shall turn away from My signs those who are big with pride on the earth, without justice, and although they may see every sign, they will not believe therein; and if they see the path of rectitude they will not take it as their path, and if they see the path of error they will take it for their path. This is because they belied Our signs, and they were ever negligent thereof. 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
