Sulaym ibn Qays mentioned that Ali (a.s) on the days of Jamal Siffin and Nehrwan, when he fought against the enemy, got on his mule which was the mule of the Holy Prophet (S.A.W), turned towards the Qibla, and recited the following Dua:
“O Allah, hands are raised towards you, eyes have been raised high, and the hearts have turned to you, and the steps moved forward. O our Lord, give victory with Truth among us and our community. You are the best Giver of Victory.”
At that time both his hands were raised high, and his companions kept saying Amen.
