Musnad Ahmad 352:1

Abu Abd al-Rahman narrated to us, he said: Sa'id ibn Abi Ayyub narrated to us, he said: Bakr ibn 'Amr narrated to me, from Abdullah ibn Hubayrah, from Abd al-Rahman ibn Jubayr, that a man who served the Messenger of Allah (may Allah bless him and grant him peace) for eight years narrated to him, that he heard the Prophet (may Allah bless him and grant him peace), when food was brought near to him, say: "In the name of Allah." And when he finished his food, he said: "O Allah, You have fed and You have given to drink, and You have enriched and You have satisfied, and You have guided and You have given life, so to You is the praise for what You have given."
