عَنِ ابْنِ أَعْبُدَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ لِي عَلِيُّ بْنُ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ يَا ابْنَ أَعْبُدَ هَلْ تَدْرِي مَا حَقُّ الطَّعَامِ قَالَ قُلْتُ وَمَا حَقُّهُ يَا ابْنَ أَبِي طَالِبٍ قَالَ تَقُولُ بِسْمِ اللَّهِ اللَّهُمَّ بَارِكْ لَنَا فِيمَا رَزَقْتَنَا قَالَ وَتَدْرِي مَا شُكْرُهُ إِذَا فَرَغْتَ قَالَ قُلْتُ وَمَا شُكْرُهُ قَالَ تَقُولُ الْحَمْدُ لِلَّهِ الَّذِي أَطْعَمَنَا وَسَقَانَا
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.)
