The Book About the Etiquette of Eating
Saying Bismillah Before and Al-Hamdulillah After Eating
عَنْ عُمَرَ بْنِ أبى سَلَمَةَ رضى اللَّه عَنْهُمَا قَالَ: قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ: سَمِّ اَللَّهَ وَكُلْ بِيَمِينِكَ، وَكُلْ مِمَّا يَلِيكَ . ((مُتَّفَقٌ عَلَيْهِ))
'Umar bin Abu Salamah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ), said to me, "Mention Allah's Name (i.e., say Bismillah before starting eating), eat with your right hand, and eat from what is near you." [Al-Bukhari and Muslim].
