So whenever the Israeli would drink it, it would be water, and whenever the Coptic would drink it, it would be blood, and the Coptic was saying to the Israeli, ‘Take some water in your mouth and pour it into my mouth’. But, when he poured it into the mouth of the Coptic, it would transform into blood. So they panicked in intense panic and they said to Musa -as , ‘If Allah -azwj was to Lift the blood from us, we would send the Children of Israel with you -as ’.
So Allah -azwj Sent the Pestilence upon them, and it is the (red) hailstorm, and it had not been seen (in those parts) before that. So they died during it (in great numbers), and they panicked with intense panic and it hit them what they had not reckoned before it, and they said, Supplicate to your Lord for us with what He Pacted with you. So if you remove the Pestilence from us we will believe you and send the Children of Israel with you’ [7:134] .

So Haman said to him -la , ‘I had prevented you -la from freeing the Children of Israel, and they have (now) gathered to him -as . So Pharaoh -la panicked and sent collectors into the cities, and went out seeking Musa -as .
