Musnad Ahmad 9:0

Narrated Sa’id ibn Zayd ibn ‘Amr ibn Nufayl: The Messenger of Allah (ﷺ) said: "Ten are in Paradise: Abu Bakr is in Paradise, ‘Umar is in Paradise, ‘Uthman is in Paradise, ‘Ali is in Paradise, Talhah is in Paradise, az-Zubayr is in Paradise, ‘Abd ar-Rahman is in Paradise, Sa’d is in Paradise, and Sa’id is in Paradise." He said: If I wished, I would have named the tenth. They said: "Who is he?" He remained silent. He said: "He is Sa’id ibn Zayd."
