Sayyiduna Abu Umamah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) taught me what to say on finishing a meal. He (peace and blessings be upon him) said: Say: "O Allah, You have fed us, given us drink and quenched our thirst, so to You belongs all praise; Your favour is never exhausted, it is not abandoned, and we are never independent of You."
