۞ 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 Musa came at Our appointed time and his Lord spoke to him, he said: My Lord! show me (Thyself), so that I may look upon Thee. He said: You cannot (bear to) see Me but look at the mountain, if it remains firm in its place, then will you see Me; but when his Lord manifested His glory to the mountain He made it crumble and Musa fell down in a swoon; then when he recovered, he said: Glory be to Thee, I turn to Thee, and I am the first of the believers. 143 He replied, "Moses, I have chosen you of all mankind for My messages and My Words. Hold fast to what I have given you, and be among the grateful!" 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 revelations those who magnify themselves wrongfully in the earth, and if they see each token believe it not, and if they see the way of righteousness choose it nor for (their) way, and if they see the way of error choose if for (their) way. That is because they deny Our revelations and are used to disregard 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
