ABUDAWUD 3767:
from ʿĀʾishah —
The Messenger of Allah ﷺ said: When one of you eats, he should mention Allah's name; if he forgets to mention Allah's name at the beginning, he should say: "In the name of Allah at the beginning and at the end of it."
أبو داود ٣٧٦٧:
عن عاءشه —
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللَّهِ تَعَالَى فَإِنْ نَسِيَ أَنْ يَذْكُرَ اسْمَ اللَّهِ تَعَالَى فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ
