“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).’” – Sound Chain
أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ أَنْبَأَنَا هِشَامٌ عَنْ بُدَيْلٍ عَنْ عَبْدِ اللَّهِ بْنِ عُبَيْدِ بْنِ عُمَيْرٍ عَنْ عَائِشَةَ
أَنَّ النَّبِيَّ ﷺ كَانَ يَأْكُلُ طَعَامًا فِي سِتَّةِ نَفَرٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ النَّبِيُّ ﷺ أَمَا إِنَّهُ لَوْ ذَكَرَ اسْمَ اللَّهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللَّهِ فَإِنْ نَسِيَ أَنْ يَذْكُرَ اسْمَ اللَّهِ فَلْيَقُلْ بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ – إسناده صحيح
