Hearing this, Abu Bakr told Umar, "Keep aside these extravagant talks, by Allah (s.w.t.), if Ali wishes he can kill us with his left hand without having need to use his right one. The factors in our favour being three, first he is alone and has no aide, second he is under compulsion to act under the testimony of the Prophet (s.a.w.s.) (to forebear) and he will never go against it, and third being that most of the people of tribes envy him and bear animosity towards him because their family (the infidels) have been killed at his hands, then they do not wish to establish favourable relations with him. And if these factors would not have been there, certainly the Caliphate would have gone to him and our opposition would be useless. O son of Khattab ! Pay attention, that Ali bin Abi Talib (a.s.), as written in his letter, is not inclined towards this world and he flees from the life of this world, while we are frightful of death and flee from it, and how will such a man fear death ………. (until the end)".
