Why did Allah Almighty state that Moses' staff was "as if it were a jann" even though it transformed into a real snake?

Moses' staff transformed into a real snake through a tangible miracle. It devoured the ropes of Pharaoh's sorcerers, which had appeared to people as snakes, causing the sorcerers to submit. Allah's statement, "as if it were a jann (a small, nimble snake)," is a simile comparing it to a type of snake, not a denial of its real transformation, as evidenced by other verses such as "and behold, it was a serpent, moving rapidly." Furthermore, the sea parted by it, and water burst forth from the stone.
