7:143 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 you shall 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.'
7:144 He said, 'Moses, I have chosen you from all mankind with My Messages and My Words. Therefore, take what I have given you, and be among the thankful.'
