Sahl bin Mu`adh bin Anas narrated from his father that: The Messenger of Allah (ﷺ) said: “Whoever eats food and then says: ‘All praise is due to Allah who fed me this and granted it as provision to me, without any effort from me nor power, (Al-ḥamdulillāh, alladhī aṭ`amanī hādha wa razaqanīhi min ghairi ḥawlin minnī, wa lā quwwatin)’ his past sins shall be forgiven.”
