A’di, the son of the well-known Haatim Taai, was one of the sincere and loyal companions of Amirul Mu'mineen (a.s.). From the year 10 A.H. when he accepted Islam, A’di had always remained in the service of the Imam (a.s.), and had fought alongside him in the battles of Jamal, Siffeen and Nahrawaan. In the battle of Jamal he sustained an injury to one of his eyes as a result of which he lost his vision.
Once he came to Mua'wiyah for some purpose. Mua’wiyah asked him why he had not brought his sons with him.
“They were killed while fighting alongside Amirul Mu'mineen (a.s.),” he replied.
“Ali has not been just to you, for he sent your sons to be killed while he has kept his own sons alive!” said Mua’wiyah.
A’di retorted, “(On the contrary) I have not done justice to Ali for he has been killed, whereas I am still alive. O’ Mua'wiyah! Our rage towards you still smoulders in our hearts. Do know that (the pain of) having our throats slit or the agony of death is easier for us to bear than hearing bad comments about Ali (a.s.).”
