Ash-Shama'il Al-Muhammadiyah, Book 28, Hadith 188 (In-Book) ⓘ

Abu Ayyub Ansaari Radiyallahu'Anhu reports: "We were once present in the assembly of Rasulullah Sallallahu 'Alayhi Wasallam. Food was brought to him. 1 did not observe any food that had so much barakah at the beginning and at the end of which there was no barakah left in the food. We therefore asked Rasulullah Sallallahu 'Alayhi Wasallam reason?. He replied: 'In the beginning we all recited 'Bismillah' before we began eating. Then someone in the end joined us, and did not recite ''Bismillah'. The shaitaan ate with him'".

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ‏:‏ حَدَّثَنَا ابْنُ لَهِيعَةَ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ رَاشِدِ بْنِ جَنْدَلٍ الْيَافِعِيِّ، عَنْ حَبِيبِ بْنِ أَوْسٍ، عَنْ أَبِي أَيُّوبَ الأَنْصَارِيِّ، قَالَ‏:‏ كُنَّا عِنْدَ النَّبِيِّ صلى الله عليه وسلم، يَوْمًا، فَقَرَّبَ طَعَامًا، فَلَمْ أَرَ طَعَامًا كَانَ أَعْظَمَ بَرَكَةً مِنْهُ، أَوَّلَ مَا أَكَلْنَا، وَلا أَقَلَّ بَرَكَةً فِي آخِرِهِ، قُلْنَا‏:‏ يَا رَسُولَ اللهِ، كَيْفَ هَذَا‏؟‏ قَالَ‏:‏ إِنَّا ذَكَرْنَا اسْمَ اللهِ حِينَ أَكَلْنَا، ثُمَّ قَعَدَ مَنْ أَكَلَ وَلَمْ يُسَمِّ اللَّهَ تَعَالَى فَأَكَلَ مَعَهُ الشَّيْطَانُ‏.‏
