“The Messenger of Allah (ﷺ) was
eating food with six of his Companions when a Bedouin came and ate it
all in two bites. The Messenger of Allah (ﷺ) said: ‘If he had
said
Bismillah, it would have sufficed you (all). When any one of you
eats
food, let him say Bismillah, and if he forgets to say Bismillah
at the
beginning, let him say Bismillah fi awwalihi wa akhirih (In
the Name
of Allah at the beginning and at the end).’”
Sunan Ibn Majah Book 29, Hadith 14
