[Machine] The Messenger of Allah ﷺ used to eat with six of his companions. Then a hungry Bedouin came and he fed him with two morsels. The Prophet ﷺ said, "If he had mentioned the name of Allah, it would have sufficed you all. So when any of you eats, let him mention the name of Allah. And if he forgets to mention it at the beginning, then let him say 'Bismillah' (in the name of Allah) at the beginning and at the end." This is the wording of the Hadith of Ruwah ibn 'Ubada.
رَسُولَ اللهِ ﷺ كَانَ يَأْكُلُ فِي سِتَّةٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ جَائِعٌ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ النَّبِيُّ ﷺ أَمَا إِنَّهُ لَوْ ذَكَرَ اسْمَ اللهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللهِ فَإِنْ نَسِيَ أَنْ يُسَمِّيَ فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ لَفْظُ حَدِيثِ رَوْحِ بْنِ عُبَادَةَ
