Chapter: What one should say after finishing one's meal.
باب مَا يَقُولُ إِذَا فَرَغَ مِنْ طَعَامِهِ
Sahih al-Bukhari 5459

Narrated Abu Umama:

Whenever the Prophet (ﷺ) 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 favor cannot by compensated or denied." Once he said, upraise be to You, O our Lord! Your favor cannot be compensated, nor can be left, nor can be dispensed with, O our Lord!"

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 ‏"‏‏.‏
