What brought you here?

He said: We came to drink the water that you prohibited us

He replied: You can drink..

Nafi' then replied: I drink and Al-Hussayn and the rest of his companions are thirsty?

The criminal said: No way that they drink. We are here to prohibit them from the water!

But this, did not stop the heroes from the companions of Imam Al-Hussayn (peace be upon him), and mocked of his words, they broke into the Euphrates to fill their water skins. 'Amru Bin Al-Hajjaj railed in their faces with a detachment of his soldiers, but the hero of Karbala; Aba Al-Fadl (peace be upon them) and Nafi' Bin Hilal faced them and there was a battle between them, but no one was killed on both sides, and the companions of Imam lead by Aba Al-Fadl (peace be upon him) returned to the camps with their full water skins.
