From 'Aishah that the Messenger of Allah ﷺ said: "When one of you eats food, then let him say: 'Bismillah.' If he forgets in the beginning, then let him say: 'Bismillah Fi Awwalihi Wa Akhirih (In the Name of Allah in its beginning and its end.)" (Using translation from Tirmidhī 1858)
قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلْيَقُلْ بِسْمِ اللَّهِ فَإِنْ نَسِيَ فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ فِي أَوَّلِهِ وَآخِرِهِ»
