Allah (SWT) says in the noble Qur’an:
They said, "Moses, will you throw something down or shall we be the ones to throw," He said, "You throw!" So when, they charmed people's eyes and overawed them. They produced a splendid sihr. And We revealed to Moses: 'Cast thy staff,' And lo, it forthwith swallowed up their lying invention, So the truth came to pass, and false was proved what they were doing, So they were vanquished there, and they turned about, humbled. And the sorcerers were cast down, bowing themselves. They said, 'We believe in the Lord of Moses and Aaron’.
They said, "Moses, either you will cast (something) or shall we be the first to cast (a spell)? It seemed to him under the effect of their sihr that their ropes and stuff were sliding.”
