فَإِذَا هِىَ ثُعْبَانٌ مُّبِينٌ
(and behold! It was a ï´¿Thu`banï´¾ serpent, manifest!) â€This ï´¿Thu`banï´¾ refers to male snakes. The snake opened its mouth and headed towards Fir`awn to swallow him, placing its lower jaw on the ground and its upper jaw reaching the (top of the) wall of the palace. When Fir`awn saw the snake, he was frightened, so he jumped and wet himself and he never wet himself before this incident. He cried, `O Musa! Take it away and I will believe in you and release the Children of Israel to you.' So Musa, peace be on him, took it, and it became a staff again. ''
