Musnad Ahmad 1:65

'Abd al-Razzaq narrated to us, Sufyan informed us, from 'Amr ibn Murrah, from Abu 'Ubaydah, from Abu Bakr, who said: Abu Bakr stood up one year after the death of the Messenger of Allah (peace and blessings of Allah be upon him) and said: The Messenger of Allah (peace and blessings of Allah be upon him) stood among us one year ago and said: "The son of Adam has not been given anything better than *'afiyah* (well-being/security). So ask Allah for *'afiyah*. And you must be truthful and righteous, for they are both in Paradise. And beware of lying and wickedness, for they are both in the Fire."
