Musnad Ahmad 33:284

Abu Mu'awiyah narrated to us, 'Asim al-Ahwal narrated to us, from Abu Nadrah, from Jabir ibn 'Abdullah, who said: "We went out with the Prophet, peace and blessings of Allah be upon him, and among us were those who were fasting, and among us were those who were not fasting, and none of us would criticize the other."
