And when Moses had completed the term and was traveling with his family, he perceived from the direction of the mount a fire. He said to his family, "Stay here; indeed, I have perceived a fire. Perhaps I will bring you from there [some] information or burning wood from the fire that you may warm yourselves."
But when he came to it, he was called from the right side of the valley in a blessed spot - from the tree, "O Moses, indeed I am Allah, Lord of the worlds."
And [he was told], "Throw down your staff." But when he saw it writhing as if it was a snake, he turned in flight and did not return. [Allah said], "O Moses, approach and fear not. Indeed, you are of the secure.
Insert your hand into the opening of your garment; it will come out white, without disease. And draw in your arm close to you [as prevention] from fear, for those are two proofs from your Lord to Pharaoh and his establishment. Indeed, they have been a people defiantly disobedient."
He said, "My Lord, indeed, I killed from among them someone, and I fear they will kill me.
And my brother Aaron is more fluent than me in tongue, so send him with me as support, verifying me. Indeed, I fear that they will deny me."
[Allah] said, "We will strengthen your arm through your brother and grant you both supremacy so they will not reach you. [It will be] through Our signs; you and those who follow you will be the predominant."
