Tarikh al Tabari v4 p509
Mawla Ali said to Zubair: "You have come to seek revenge for Uthman, while it was you who killed him." And Mawla Ali said to Talha: "Why do you disrespect the Prophet by bringing his wife to the Battle of the Camel while keeping your own wife at home
وكان عليٌّ قال للزبير: أتطلب مني دمَ عثمان وأنت قتلته! سلّط الله على أشدّنا عليه اليومَ ما يكره. وقال عليٌّ: يا طلحة، جئت بعِرس رسول الله صلى الله عليه وسلم تقاتل بها وخبّأت عِرسك في البيت! أما بايعتني! قال: بايعتُك وعلى عُنقي اللُّجّ

Ibn Hatib said: “I came with Ali on the Day of the Camel to the howdah, and it was like the spines of a hedgehog because of the arrows. He struck the howdah and then said: ‘Indeed, this Humayra wanted to kill me just as she killed Uthman ibn Affan.’ Her brother Muhammad said to her, ‘Have you been struck by anything?’ She replied, ‘An arrowhead in my upper arm.’ He put his head inside, then pulled her toward him and removed it.
عن ابن حاطب قال: أقبلت مع علي يوم الجمل إلى الهودج وكان شوك القنفذ من النبل، فضرب الهودج، ثم قال: إن حميراء إرم هذه أرادت أن تقتلني كما قتلت عثمان بن عفان. فقال لها أخوها محمد: هل أصابك شيء؟ فقالت: مشقص في عضدي. فأدخل رأسه ثم جرها إليه فأخرجه


Al-Hasan al-Basri said:
“Talha and al-Zubayr came to Basra, and the people asked them, ‘What has brought you here?’ They replied, ‘We seek [vengeance for] the blood of Uthman.’ Al-Hasan said, ‘Glory be to Allah! Did the people have no sense to say, “By Allah, none killed Uthman but you.
قال: سمعت الحسن يقول: جاء طلحة والزبير إلى البصرة، فقال لهم الناس: ما جاء بكم؟ قالوا: نطلب دم عثمان. قال الحسن: أيا سبحان الله! أفما كان للقوم عقول فيقولون: والله ما قتل عثمان غيركم
