Musnad Ahmad 9:7

Waki’ narrated to us, Shu’bah narrated to us, from al-Hurr ibn al-Sayyah, from ‘Abd al-Rahman ibn al-Akhnas, who said: Al-Mughirah ibn Shu’bah delivered a sermon to us and spoke ill of ‘Ali, may Allah be pleased with him. Sa’id ibn Zayd stood up and said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "The Prophet is in Paradise, Abu Bakr is in Paradise, ‘Umar is in Paradise, ‘Uthman is in Paradise, ‘Ali is in Paradise, Talhah is in Paradise, al-Zubayr is in Paradise, ‘Abd al-Rahman ibn ‘Awf is in Paradise, and Sa’d is in Paradise." And if I wished, I could name the tenth.
