Musannaf Ibn Abi Shaybah 40472 — Reports on Uthman (may Allah be)

It is narrated from Hakim bin Jabir that when Sayyiduna Uthman (may Allah be pleased with him) was besieged, Sayyiduna Ali (may Allah be pleased with him) came to Sayyiduna Talhah (may Allah be pleased with him), who was sitting in his house leaning on cushions. Sayyiduna Ali said: I adjure you to turn back the people (the rebels) from Amir al-Mu'minin, for he will be killed. Sayyiduna Talhah said: By Allah, I will not turn them back until Banu Umayyah give the people their right from what is with them.
