The verses from Surat Ta-Ha, which are as follows (interpretation of the meaning):

“They said: ‘O Musa! Either you throw first or we be the first to throw?’

[Musa] said: ‘Nay, throw you (first)!’ Then behold! their ropes and their sticks, by their magic, appeared to him as though they moved fast.

So Musa conceived fear in himself.

We (Allah) said: ‘Fear not! Surely, you will have the upper hand.

And throw that which is in your right hand! It will swallow up that which they have made. That which they have made is only a magician’s trick, and the magician will never be successful, to whatever amount (of skill) he may attain’” [20:65-69]
