Umayyah was sitting and a man was eating. He did not mention Allah's name until there remained the last morsel. When he raised it to his mouth, he said: In the name of Allah at the beginning and at the end of it. The Prophet ﷺ laughed and said: The devil kept eating along with him, but when he mentioned Allah's name, he vomited what was in his belly. Abu Dawud: Jabir bin Subh is grandfather of Sulaiman bin Harb from his mother's side.  

عَنْ عَمِّهِ أُمَيَّةَ بْنِ مَخْشِيٍّ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ جَالِسًا وَرَجُلٌ يَأْكُلُ فَلَمْ يُسَمِّ حَتَّى لَمْ يَبْقَ مِنْ طَعَامِهِ إِلاَّ لُقْمَةٌ فَلَمَّا رَفَعَهَا إِلَى فِيهِ قَالَ بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ فَضَحِكَ النَّبِيُّ ﷺ ثُمَّ قَالَ مَا زَالَ الشَّيْطَانُ يَأْكُلُ مَعَهُ فَلَمَّا ذَكَرَ اسْمَ اللَّهِ ﷻ اسْتَقَاءَ مَا فِي بَطْنِهِ  

[Machine] In the name of Allah, at its beginning and at its end. So I asked him about that and he said, "My grandfather, Umayyah ibn Makhshiyya, narrated to me that he was a companion of the Prophet ﷺ . There was a man who used to eat with the Prophet ﷺ but he would not mention the name of Allah before eating. Then, when he was in the last morsel, he would say, 'In the name of Allah, at its beginning and at its end.' The Prophet ﷺ said, 'The devil was eating with him until he mentioned the name of Allah at the beginning and at the end, and then the devil vomited out everything he had eaten.'"  

بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ فَقُلْتُ لَهُ فِي ذَلِكَ فَقَالَ إِنَّ جَدِّي أُمَيَّةُ بْنُ مَخْشِيٍّ حَدَّثَنِي وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ رَجُلًا كَانَ يَأْكُلُ عِنْدَ النَّبِيِّ ﷺ فَلَمْ يُسَمِّ فَلَمَّا كَانَ فِي آخِرِ لُقْمَةٍ قَالَ بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ فَقَالَ النَّبِيُّ ﷺ مَا زَالَ الشَّيْطَانُ يَأْكُلُ مَعَهُ حَتَّى قَالَ أَوَّلَهُ وَآخِرَهُ فَقَاءَ الشَّيْطَانُ كُلَّ شَيْءٍ أَكَلَهُ  

[Machine] It was narrated to us by Umayyah ibn Makhshiyy, who was one of the companions of the Messenger of Allah ﷺ , that the Prophet ﷺ saw a man eating without mentioning the name of Allah. When the man was about to eat his last portion, he said "Bismillah" (In the name of Allah) at the beginning and end of it. The Messenger of Allah ﷺ said, "The devil was eating with him until he mentioned the name of Allah, and then the devil vomited what he had eaten."  

حَدَّثَنَا أُمَيَّةُ بْنُ مَخْشِيٍّ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ أَنَّ النَّبِيَّ ﷺ رَأَى رَجُلًا يَأْكُلُ وَلَمْ يُسَمِّ فَلَمَّا كَانَ فِي آخِرِ لُقْمَةٍ قَالَ بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ قَالَ رَسُولُ اللهِ ﷺ «مَا زَالَ الشَّيْطَانُ يَأْكُلُ مَعَهُ فَلَمَّا سَمَّى قَاءَ الشَّيْطَانُ مَا أَكَلَ»
