Moses’ Staff Turning to a Snake

The staff of Moses was one of the great miracles that Allah performed to support his prophet. (And what is that in your right hand, O Moses?"
He said, "It is my staff; I lean upon it, and I bring down leaves for my sheep and I have therein other uses.")
Allah turned the staff into a great snake: ([Allah] said, "Throw it down, O Moses.” So he did, then—behold! —it became a serpent, slithering. Allah said, “Take it, and have no fear. We will return it to its former state.) The snake was able to eat the snakes conjured by the magicians of the Pharaoh. (Cast what is in your right hand, and it will swallow up what they have made, for what they have made is no more than a magic trick. And magicians can never succeed wherever they go.”). The size of the snake was not mentioned as it is irrelevant to the story.
