When Ubaidullah Ibn Utbah mentioned to Ibn Abbas that Aisha said "In his death-illness the Prophet was brought to (Aisha's) house while his shoulders were being supported by Fadhl Ibn Abbas and another person", then Abdullah Ibn Abbas said: "Do you know who this 'other man' was?" Ibn Utbah replied: "No." Then Ibn Abbas said: "He was Ali Ibn Abi Talib, but she is averse to name him in a good context."

"Hadhrath Ayesha, could not bear hearing a good thing about 'Ali, and this is solid evidence of her being an enemy of Ali, for Nasibis to proclaim that the narrators of these Hadith are weak, is not a valid excuse, because this is testified in the annals of history".

"Muammar narrates that Ayesha was never happy narrating anything good about 'Ali, Zuhri narrates that Ayesha did not possess the ability to say anything good of 'Ali".
Hadhrath Ali said, "Ayesha fought me because firstly being a woman she possessed a weak judgement and secondly she bore enmity towards me and it would open in the same way a pot is opened. She would have never fought anyone other than me in that way"
