Musannaf Ibn Abi Shayba 23:85

Hussain bin Ali narrated to us, from Za'idah, from al-Hasan, from Jabir bin Abdullah, that he said: It was said, "O Messenger of Allah, which deeds are best?" He said, "Patience and generosity." It was said, "Which of the believers are most complete in faith?" He said, "Those of them who are best in character."
