They do not wait aught but that the angels should come to them, or that your Lord should come, or that some of the signs of your Lord should come. On the day when some of the signs of your Lord shall come, its faith shall not profit a soul which did not believe before, or earn good through its faith. Say: Wait; we too are waiting.

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.
