وعن أمية بن مخشى الصحابي رضى الله عنه
قال: كان رسول الله صلى الله عليه وسلم جالساً، ورجل يأكل، فلم يسم الله حتى لم يبق من طعامه إلا لقمة، فلما رفعها إلى فيه، قال: بسم الله أوله وآخره، فضحك النبي صلى الله عليه وسلم، ثم قال: «ما زال الشيطان يأكل معه، فلما ذكر اسم الله استقاء ما فيه بطنه»
Messenger of Allah (sallallahu alayhi wa sallam) was sitting while a man was eating food. That man did not mention the Name of Allah (before commencing to eat) till only a morsel of food was left.
When he raised it to his mouth, he said: “Bismillah awwalahu wa akhirahu (With the Name of Allah, in the beginning and in the end).” Messenger of Allah (sallallahu alayhi wa sallam) smiled at this and said, “Satan had been eating with him but when he mentioned the Name of Allah, Satan vomited all that was in his stomach.”.
