حَدَّثَنَا يَحْيَى بْنُ مُوسَى، قَالَ: حَدَّثَنَا أَبُو دَاوُدَ، قَالَ: حَدَّثَنَا هِشَامٌ الدَّسْتُوائِيُّ، عَنْ بُدَيْلٍ الْعُقَيْلِيُّ، عَنْ عَبْدِ اللهِ بْنِ عُبَيْدِ بْنِ عُمَيْرٍ، عَنْ أُمِّ كُلْثُومٍ، عَنْ عَائِشَةَ
قَالَتْ: قَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا أَكَلَ أَحَدُكُمْ، فَنَسِيَ أَنْ يَذْكُرَ اللَّهَ تَعَالَى عَلَى طَعَامِهِ، فَلْيَقُلْ: بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ»
“The Messenger of Allah (sallallahu alayhi wa sallam) said (sallallahu alayhi wa sallam): ‘If one of you eats and forgets to mention Allah (Exalted is He) during his meal, let him say: Bismillah awwalahu wa akhirahu, which means, ‘In the name of Allah at its beginning and at its end’.’”
