Taha 20:70

Faolqiya assaharatu sujjadanqaloo amanna birabbi haroona wamoosa

So the magicians fell down in prostration. They said, "We have believed in the Lord of Aaron and Moses."

So, the magicians were led (by the truth) to fall in prostration. They said, “We have (now) believed in the Lord of Hārūn and Mūsā.”
