Musnad Ahmad 28:176

Hassan narrated to us, Ibn Lahi'ah narrated to us, from al-Harith ibn Yazid al-Hadrami, from Abdullah ibn Amr, that the Messenger of Allah, may Allah bless him and grant him peace, said: "Four things, if they are in you, then it does not matter what you have missed of the world: safeguarding a trust, truthfulness in speech, good character, and chastity in food."
