How Fir`awn drowned

Mastabat Fira'wn

The Children of Israel left Egypt in the company of Hazrat Musa (A.S). It was said that there were six hundred thousand soldiers, plus offspring. They borrowed a lot of ornaments and took that with them. Fir`awn was very angry with them. He was filled with great pride and with massive armies. No one that had any authority remained behind in Fir`awn's kingdom. They were all together . The companions of Hazrat Musa (A.S) said: "We are sure to be overtaken.When The two groups met face to face. The people with Hazrat Musa kept asking, "How can we be saved today'' Hazrat Musa (A.S) replied, Nay, verily, with me is my Lord. He will guide me. It had been so difficult, but it suddenly became easy. Allah commanded him to strike a dry path for them in the sea .He did and the sea was cleft asunder, each part stood like a mighty mountain.
The sea was split into twelve paths, each route for each Israelite tribe. Allah then commanded the wind and the path was dry for them. The water in between the paths appeared as windows and every tribe was able to see the other so they would not think that others were destroyed.
The Children of Israel crossed the sea. When the last one crossed, Fir`awn and his soldiers had arrived at the edge of the other shore. There were one hundred thousand black horses . Fir`awn was frightened when he saw the see. He wanted to turn back. The prayer of Hazrat Musa (A.S) was answered. Hazrat Jibril (A.S) passed by Fir`awn's horse. And then Jibril rushed into the sea, and Fir`awn did the same behind him. Hazrat Jibril (A.S) no longer had any control .
He said: "O ‘people do not have more right in the sea.'' So they rushed into the sea. When they all were in the sea and the first of them was about to emerge on the other side, Allah, the commanded the sea to strand them. The sea closed over them . The waves accumulated above Fir`awn and he was overwhelmed by the stupors of death.At that time he said:
“I believe that none has the right to be worshipped but Allah in Whom the Children of Israel believe, and I am one of the Muslims.
Some of the Children of Israel doubted the death of Fir`awn so Allah commanded the sea to throw his body. . The body was thrown to a high place on the land so that the Children of Israel could confirm his death ''

Hadith
Allah's Messenger said;
“Jibril said to me, "If you could have seen me while I was taking black mud from the sea and placing into the mouth of Fir`awn out of fear that the mercy would reach him.'' anger.
Fir`awn and his people were destroyed on the day of `Ashura'.When the Prophet arrived at Al-Madinah he asked,
What is this day that you are fasting) They responded `This is the day in which Hazrat Musa (A.S) was victorious over Fir`awn.' So the Prophet said,
“You have more right to Hazrat Musa (A.S) than they, so fast it.”
