Musannaf Ibn Abi Shayba 33:61

Jarir narrated to us, from Qabus, from his father, from Ibn Abbas, who said: Musa said: "O my Lord, which of Your servants is most beloved to You?" He said: "The one who remembers Me the most." He said: "Which of Your servants is the richest?" He said: "The one who is content with what I have given him." He said: "O my Lord, which of Your servants is the wisest?" He said: "The one who judges himself as he judges others."
