Sunan Abi Dawud Book 42, Hadith 53
Abdullah ibn Zalim al-Mazini said: I heard Sa'id ibn Zayd ibn Amr ibn Nufayl say: When so and so came to Kufah, and made so and so stand to address the people, Sa'id ibn Zayd caught hold of my hand and said: Are you seeing this tyrant? I bear witness to the nine people that they will go to Paradise. If I testify to the tenth too, I shall not be sinful.
I asked: Who are the nine? He said: The Messenger of Allah (ﷺ) said when he was on Hira': Be still, Hira', for only a Prophet, or an ever-truthful, or a martyr is on you. I asked: Who are those nine? He said: The Messenger of Allah, AbuBakr, Umar, Uthman, Ali, Talhah, az-Zubayr, Sa'd ibn AbuWaqqas and AbdurRahman ibn Awf. I asked: Who is the tenth? He paused a moment and said: it is I.
Abu Dawud said: This tradition has been transmitted by al-Ashja'i, from Sufyan, from Mansur, from Hilal b. Yasaf, from Ibn Hayyan on the authority of 'Abd Allah b. Zalim through his different chain of narrators in a a similar manner.
The caliphate of Prophecy will last thirty years; then Allah will give the Kingdom to whom he wishes; or his kingdom to whom he wishes.
AbdurRahman ibn al-Akhnas said that when he was in the mosque, a man mentioned Ali (may Allah be pleased with him). So Sa'id ibn Zayd got up and said: I bear witness to the Messenger of Allah (ﷺ) that I heard him say: Ten persons will go to Paradise: The Prophet (ﷺ) will go to Paradise, AbuBakr will go to Paradise, Umar will go to Paradise, Uthman will go to Paradise, Ali will go to Paradise, Talhah will go to Paradise: az-Zubayr ibn al-Awwam will go to paradise, Sa'd ibn Malik will go to Paradise, and AbdurRahman ibn Awf will go to Paradise. If I wish, I can mention the tenth. The People asked: Who is he: So he kept silence. The again asked: Who is he: He replied: He is Sa'id ibn Zayd.
