Before and after eating duas

Naming Allah at the start keeps the meal from the share of Shaytan.

بِسْمِ اللَّهِ

Bismillāh

In the name of Allah.

If forgotten at the start, say: Bismillāhi awwalahu wa ākhirahu — In the name of Allah, at its beginning and its end.

Thanks after eating is a cause for forgiveness.

الْحَمْدُ لِلَّهِ الَّذِي أَطْعَمَنِي هَذَا وَرَزَقَنِيهِ مِنْ غَيْرِ حَوْلٍ مِنِّي وَلَا قُوَّةٍ

Al-ḥamdu lillāhi alladhī aṭʿamanī hādhā wa razaqanīhi min ghayri ḥawlin minnī wa lā quwwah

All praise is for Allah, who fed me this and provided it for me without any strength or power on my part.
