Musannaf Ibn Abi Shaybah 36125 — Book of History

Sayyiduna Jarir (may Allah be pleased with him) said: I heard Sayyiduna Mu'awiyah (may Allah be pleased with him) delivering a sermon, saying that at the time of his death the blessed age of the Messenger of Allah (peace and blessings be upon him) was sixty-three years, that of the two Shaykhs, Abu Bakr and Umar (may Allah be pleased with them both), was sixty-three years, and "I too have reached sixty-three years."
