It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Abu Bakr and Umar (may Allah be pleased with them both) are the leaders of the mature men among the people of Paradise, of the first and the last; and O Ali, do not tell them this."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ja'far bin Muhammad except Sufyan bin Uyaynah, and Sa'id bin Isa is alone in narrating it."
