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: "The most merciful of my Ummah towards my Ummah is Abu Bakr (may Allah be pleased with him), and the most gentle in conduct is Umar bin Khattab (may Allah be pleased with him), and the most truthful in modesty among my Ummah is Uthman (may Allah be pleased with him), and the best in judgment is Ali bin Abi Talib (may Allah be pleased with him), and the most knowledgeable of what is lawful and unlawful is Mu'adh bin Jabal (may Allah be pleased with him), who on the Day of Resurrection will walk ahead of the scholars by the distance of a bowshot, and the best reciter among my Ummah is Ubayy bin Ka'b (may Allah be pleased with him), and the most knowledgeable of inheritance laws is Zayd bin Thabit (may Allah be pleased with him), and 'Awaimir has been given the ability for worship (that is, Abu Darda' (may Allah be pleased with him)). May Allah be pleased with them all."
