[Machine] About this, my grandfather Umayyah ibn Makhshiyy, who was one of the companions of the Prophet Muhammad ﷺ , heard him say: "There was a man who used to eat while the Prophet ﷺ was looking at him, but he did not mention the name of Allah until there was only one morsel of food left. Then he said, 'In the name of Allah' at the beginning and the end. The Prophet ﷺ said, 'The devil kept eating with him until he mentioned the name of Allah, and then there was nothing left in his stomach except what he vomited.'"  

عَنْ ذَلِكَ إِنَّ جَدِّي أُمَيَّةَ بْنَ مَخْشِيٍّ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ سَمِعْتُهُ يَقُولُ إِنَّ رَجُلًا كَانَ يَأْكُلُ وَالنَّبِيُّ ﷺ يَنْظُرُ فَلَمْ يُسَمِّ حَتَّى كَانَ فِي آخِرِ طَعَامِهِ لُقْمَةٌ فَقَالَ بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ فَقَالَ النَّبِيُّ ﷺ مَا زَالَ الشَّيْطَانُ يَأْكُلُ مَعَهُ حَتَّى سَمَّى فَلَمْ يَبْقَ فِي بَطْنِهِ شَيْءٌ إِلَّا قَاءَهُ
