Musannaf Ibn Abi Shayba 33:126

Isma'il ibn Ibrahim narrated to us, from al-Jurayri, from Abu Nadra, who said: The Messenger of Allah (may Allah bless him and grant him peace) and a group of his companions ate a meal of barley bread that had not been sifted, with meat, and they drank from a stream. He said: "This is a meal of the bounties (ni'am) that you will be asked about on the Day of Resurrection."
