Abd al-Rahman bin Jubayr bin Nufayr narrates from his father that he said: I said to Sayyiduna Hasan bin Ali (may Allah be pleased with them both): People are saying that you want the caliphate. He said: "The chiefs of the Arabs were in my hand; they would fight whomever I fought and make peace with whomever I made peace with. I gave it up seeking the pleasure of Allah Almighty and to spare the blood of the Ummah of Muhammad (peace and blessings be upon him). Shall I then (now) seize it back by means of the billy-goats (i.e. the lowly men) of the people of the Hijaz?!" This chain is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
