Abu Umaamah Radiyallahu-'Anhu says:
"When the dastarkhaan (table cloth) was being removed in the presence of Rasulullah Sallailahu 'Alayhi Wasallam, Rasulullah Saliallahu 'Alayhi Wasallam recited this du'aa:Alhamdulillaahi hamdan kathiran tayyiban mubaarakan fihi-ghayra mu-wadda-in wa-laa mus-taghnan 'anhu rabbuna.
