Musnad Ahmad 1237:10

'Attab narrated to us, he said: 'Abdullah narrated to us, he said: Sa'id ibn Yazid narrated to us, from Yazid ibn Abi Habib, from Kulayb ibn Dhuhl, from 'Ubayd ibn Jabr, who said: I rode with Abu Basrah from Al-Fustat to Alexandria in a ship. When we pushed off from our mooring, he ordered his food mat, and it was brought near. Then he invited me to lunch, and that was in Ramadan. I said: "O Abu Basrah, by Allah, have our houses not yet disappeared from our sight?" He said: "Do you turn away from the Sunnah of the Messenger of Allah (ﷺ)?" I said: "No." He said: "Then eat." So we remained breaking our fast until we reached our destination.
