It is narrated from Sayyiduna Abu Juhayfah (may Allah be pleased with him) 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 middle-aged people of Paradise, of the first and the last, except the prophets and the messengers."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Malik except Khunays; Zakariyya bin Yahya is alone in narrating it; and this narration is narrated from Ibn Abi Juhayfah only with this chain."
