Musnad Ahmad 1237:9

Abu Abd al-Rahman narrated to us, he said: Sa'id ibn Abi Ayyub narrated to us, he said: Yazid ibn Abi Habib narrated to me, that Kulayb ibn Dhuhl informed him, from Ubayd—meaning Ibn Jabr—he said: I rode with Abu Basrah al-Ghifari, a companion of the Messenger of Allah (peace and blessings of Allah be upon him), in a ship from al-Fustat during Ramadan. Then he brought his lunch near and said: "Draw near." I said: "Am I not among the houses [i.e., still within the sight of the city]?" Abu Basrah said: "Do you turn away from the Sunnah of the Messenger of Allah (peace and blessings of Allah be upon him)?"
