۞ 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 (Moses) came at the time and place appointed by Us, and his Lord spoke to him, he said: "O my Lord! Show me (Yourself), that I may look upon You." Allah said: "You cannot see Me, but look upon the mountain if it stands still in its place then you shall see Me." So when his Lord appeared to the mountain, He made it collapse to dust, and Musa (Moses) fell down unconscious. Then when he recovered his senses he said: "Glory be to You, I turn to You in repentance 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 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 I will turn away from My signs those who are arrogant upon the earth without right; and if they should see every sign, they will not believe in it. And if they see the way of consciousness, they will not adopt it as a way; but if they see the way of error, they will adopt it as a way. That is because they have denied Our signs and they were heedless of 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
