۞ 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 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 admonition of every kind and clear explanation of all things; so take hold of them with firmness and enjoin your people to take hold of what is best thereof; I will show you the abode of the transgressors. 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 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
