narrated abu umama (radi-allahu 'anhu):

whenever the dining sheet of the prophet (sallallahu 'alaihi wa sallam) was taken away (i.e., whenever he finished his meal), he used to say: "al-hamdu lillah kathiran taiyiban mubarakan fihi ghaira makfiy wala muwada' wala mustaghna'anhu rabbuna."

narrated abu umama (radi-allahu 'anhu):

whenever the prophet (sallallahu 'alaihi wa sallam) finished his meals (or when his dining sheet was taken away), he used to say. "praise be to allah who has satisfied our needs and quenched our thirst. your favor cannot by compensated or denied." once he said, praise be to you, o our lord! your favor cannot be compensated, nor can be left, nor can be dispensed with, o our lord!"
