۞ And We agreed with Moosa a covenant for thirty nights (of solitude) and completed it by adding ten to them, so the covenant of His Lord amounted to forty nights in full; and Moosa said to his brother Haroon, “Be my deputy over my people and make reform and do not allow the ways of the mischievous to enter.” 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 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 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 Those who behave arrogantly on the earth in defiance of right - them will I turn away from My signs: Even if they see all the signs, they will not believe in them; and if they see the way of right conduct, they will not adopt it as the way; but if they see the way of error, that is the way they will adopt. For they have rejected our signs, and failed to take warning from them. 146 Vain are the deeds of those who belie Our signs and the Everlasting Life. Shall they not be recompensed except for what they used to do? 147
