(The Pharaoh) threatened: "If you, (O Moses,) take any deity other than me (to worship, to offer your prayer and sacrifices to, and to seek help from), I will most certainly make you one of those imprisoned."
(Pharaoh) said, “Indeed, if you take anything besides me as god I will surely imprison you!”

"Let me warn you", Pharaoh said to Mussa, "should you take an Ilah besides me, I will shut you up with those shut up in the grim confines of the dungeon"
