Sahih Bukhari Volume 7, Book 70, Hadith 5461

حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ ثَوْرِ بْنِ يَزِيدَ، عَنْ خَالِدِ بْنِ مَعْدَانَ، عَنْ أَبِي أُمَامَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا فَرَغَ مِنْ طَعَامِهِ ـ وَقَالَ مَرَّةً إِذَا رَفَعَ مَائِدَتَهُ ـ قَالَ ‏"‏ الْحَمْدُ لِلَّهِ الَّذِي كَفَانَا وَأَرْوَانَا، غَيْرَ مَكْفِيٍّ، وَلاَ مَكْفُورٍ ـ وَقَالَ مَرَّةً الْحَمْدُ لِلَّهِ رَبِّنَا، غَيْرَ مَكْفِيٍّ، وَلاَ مُوَدَّعٍ ـ وَلاَ مُسْتَغْنًى، رَبَّنَا ‏"‏‏

Narrated By Abu Umama : Whenever the Prophet 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 favour cannot by compensated or denied." Once he said, upraise be to You, O our Lord! Your favour cannot be compensated, nor can be left, nor can be dispensed with, O our Lord!"
