His performance in the battles of Jamal and Siffin had created such impression among the Arabs that even warriors of consequence trembled at his name. Amir al-mu'minin too was proud of his courage and valour, and always placed him forward in encounters.
ash-Shaykh al-Baha'i has written in al-Kashkul that `Ali ibn Abi Talib kept him abreast in the battles and did not allow Hasan and Husayn to go ahead, and used to say, "He is my son while these two are sons of the Prophet of Allah." When a Kharijite said to Ibn al-Hanafiyyah that `Ali thrust him into the flames of war but saved away Hasan and Husayn he replied that he himself was like the right hand and Hasan and Husayn like `Ali's two eyes and that `Ali protected his eyes with his right hand.
But al-`Allamah al-Mamaqani has written in Tanqih al-Maqal that this was not the reply of Ibn al-Hanafiyyah but of Amir al-mu'minin himself.
When during the battle of Siffin Muhammad mentioned this matter to Amir al-mu'minin in a complaining tone he replied, "You are my right hand whereas they are my eyes, and the hand should protect the eyes." Apparently it seems that first Amir al-mu'minin must have given this reply and thereafter someone might have mentioned it to Muhammad ibn al-Hanafiyyah and he must have repeated the same reply as there could be no more eloquent reply than this one and its eloquence confirms the view that it was originally the outcome of the eloquent tongue of Amir al-mu'minin and was later appropriated by Muhammad al-Hanafiyyah.
Consequently, both these views can be held to be correct and there is no incongruity between them. However, he was born in the reign of the second Caliph and died in the reign of `Abd al-Malik ibn Marwan at the age of sixty-five years. Some writers have recorded the year of his death as 80 A.H. and others as 81 A.H. There is a difference about the place of his death as well. Some have put it as Medina, some Aylah and some Ta'if.
