سورة الأعراف

These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers

And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors.

Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers.

And Musa said: O Firon! surely I am an apostle from the Lord of the worlds:

(I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel

He said: If you have come with a sign, then bring it, if you are of the truthful ones.

So he threw his rod, then lo! it was a clear serpent.

And he drew forth his hand, and lo! it was white to the beholders.

The chiefs of Firon's people said: most surely this is an enchanter possessed of knowledge:

He intends to turn you out of your land. What counsel do you then give?
