۞ 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 During the appointment, the Lord spoke to Moses. He asked the Lord to show Himself so that he could look at Him. The Lord replied, "You can never see Me. But look at the mountain. If the mountain remains firm only then will you see Me." When the Lord manifested His Glory to the mountain, He turned it into dust and Moses fell down upon his face senseless. After regaining his senses, Moses said, "Lord, You are all Holy. I repent for what I asked you to do and I am the first to believe in You." 143 [Allah] said, "O Moses, I have chosen you over the people with My messages and My words [to you]. So take what I have given you and be among the grateful." 144 And We wrote for him on the tablets, the advice for all things and the details of all things; and commanded “Accept it firmly and command your people to choose its good advices; soon I shall show you people the destination of the disobedient.” 145 I will turn those away from My signs who behave unjustly with arrogance in the land so that even though they see all the signs they will not believe in them; and if they see the path of rectitude, will not take it to be a way; and if they see the way of error take it to be the (right) path. This is so for they have called Our messages lies, and have been heedless of 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
