Ibn Abaad says: Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) said to me: O Ibn Abaad, do you know what is the right of food? I said: O Ibn Abi Talib! You tell me what its right is. He said: When you eat food, say: BISMILLAH, ALLAHUMMA BARIK LANA FIMA RAZAQTANA (In the name of Allah! O Allah! Bless for us what You have provided for us). Then Sayyiduna Ali (may Allah be pleased with him) said: Well, do you know what to say when you finish eating so that its gratitude is fulfilled? I said: What should be said for its gratitude? He said: You should say: ALHAMDULILLAHILLADHI AT'AMANA WASAQANA. (All praise is for Allah who fed us and gave us drink.)
