بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ
Bismillahi awwalahu wa akhirah
In the Name of Allah, at its beginning and at its end.
The Prophet ﷺ said: "When one of you eats, let him mention the Name of Allah. If he forgets to mention the Name of Allah at the beginning, let him say: 'Bismillahi awwalahu wa akhirah.'" Forgetting is human — Islam doesn't punish you for it. Instead, it gives you a recovery phrase that retroactively covers the entire meal.
