Sayyiduna Jabir bin Abdullah al-Ansari (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The most merciful of my Ummah towards my Ummah is Abu Bakr; the gentlest of my Ummah towards my Ummah is Umar; the most truthful in modesty in my Ummah is Uthman; the most capable of giving judgement in my Ummah is Ali bin Abi Talib; the most knowledgeable of them about what is lawful and unlawful is Mu'adh bin Jabal, who will come on the Day of Resurrection ahead of the scholars by a ratwah (that is, prominently); the greatest scholar of the Qur'an in my Ummah is Ubayy bin Ka'b; the greatest scholar of inheritance is Zayd bin Thabit; and Uwaymir has been granted devotion in worship." By this the Prophet (peace and blessings be upon him) meant Sayyiduna Abu al-Darda (may Allah be pleased with him). May Allah Almighty bestow His pleasure upon all of them.
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat, and its chain is hasan (good).
