[ Musa ( Moses ) ] said : " Verily , you know that these signs have been sent down by none but the Lord of the heavens and the earth as clear ( evidences i.e. proofs of Allah 's Oneness and His Omnipotence , etc . ) . And I think you are , indeed , O Fir 'aun ( Pharaoh ) doomed to destruction ( away from all good ) ! "
