The Book About the Etiquette of Eating
Saying Bismillah Before and Al-Hamdulillah After Eating
وَعَنْ أبى أُمَامَةَ رضى اللَّه عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ كَانَ إِذَا رَفَعَ مَائِدَتَهُ قَالَ: الْحَمْدُ لِلَّهِ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ، غَيْرَ مكفى ولامودع، وَلَا مُسْتَغْنًى عَنْهُ رَبُّنَا .((رَوَاهُ البخارى))
Abu Umamah (May Allah be pleased with him) reported: Whenever the Prophet (ﷺ) finished a meal, he would say: "Al-hamdu lillahi hamdan kathiran taiyyiban mubarakan fihi, ghaira makfiyyin wa la muwadda`in, wa la mustaghnan `anhu, Rabbuna. (All praise is due to Allah, praise which is abundant, pure, and full of blessings, which is indispensable and to which one cannot be indifferent).'' [Al-Bukhari].
