۞ 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 at the appointed time and his Lord spoke to him, he said: 'Lord, let me see, that I can look at You' He replied: 'You shall not see Me. But look at the mountain; if it remains firm in its place, then shall you see Me' And when his Lord was revealed to the mountain and caused it to be crushed and leveled whereupon Moses fell down senseless, and when he recovered, he said: 'Exaltations to You! I repent to You. I am the first of 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 We wrote advice and laws for him on Tablets about all kinds of things, saying, "Follow them and command your people to follow the good advice therein, and I will show you the dwellings of the evil-doers." 145 From My signs I will turn away the unrightfully, arrogant in the land, so that even if they witness every sign they would not believe it. If they see the path of righteousness, they shall not take it as a path; but if they see the path of error, they shall take it for their path because they belied Our signs and were inattentive towards them. 146 And those who belie Our signs and the meeting of the Hereafter - vain shall be their work. They shall be requited not save for that which they wrought. 147
