۞ And We appointed for Musa (Moses) thirty nights and added (to the period) ten (more), and he completed the term, appointed by his Lord, of forty nights. And Musa (Moses) said to his brother Harun (Aaron): "Replace me among my people, act in the Right Way (by ordering the people to obey Allah and to worship Him Alone) and follow not the way of the Mufsidun (mischief-makers)." 142 And when Moses came to Our appointed time and his Lord spoke with him, he said, 'Oh my Lord, show me, that I may behold Thee!' Said He, 'Thou shalt not see Me; but behold the mountain -- if it stays fast in its place, then thou shalt see Me.' And when his Lord revealed Him to the mountain He made it crumble to dust; and Moses fell down swooning. So when he awoke, he said, 'Glory be to Thee! I repent to Thee; I am the first of the believers.' 143 (Allah) said: "O Moses! I have chosen thee above (other) men, by the mission I (have given thee) and the words I (have spoken to thee): take then the (revelation) which I give thee, and be of those who give thanks." 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 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
