Al-A'raaf — Ruku 13

Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear.

Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers.

And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient.

Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters.

And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds

[Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel."

[Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful."

So Moses threw his staff, and suddenly it was a serpent, manifest.
