Musannaf Ibn Abi Shaybah

Hazrat Habib Abi Thabit narrates that in the Battle of Siffin, the flag of Hazrat Ali (may Allah be pleased with him) was in the hands of Hashim bin Utbah. He was blind in one eye. Hazrat Ammar said, "O one-eyed! Come forward, there is no good in that one-eyed person who does not face fear." He felt shy and came forward. Hazrat Amr bin Aas said, "I am seeing an action in the one with the black flag; if he remains like this, today the Arabs will surely accomplish something." He was saying, "Every water has a watering place, and people come to the water; O servants of Allah! Be patient, Paradise is under the shade of swords."
