Bukhari

Hadith Commentary:

Based on other narrations, this supplication is also Sunnah: "Alhamdu lillahi alladhi at'amana wa saqana, wa ja'alana muslimin." After eating at someone else's house, one should supplicate for them with these words.
«اللَّهُمَّ بَارِكْ لَهُمْ فِيمَا رَزَقْتَهُمْ وَاغْفِرْ لَهُمْ وَارْحَمْهُمْ»

Hadith Commentary:
In one hadith, it is stated that whoever recites the following supplication after eating, his past sins are forgiven:
(alhamdu lillahi allathee at‘amani hadha al-ta‘ama wa razaqanihi min ghayri hawlin minni wa la quwwah)
“All praise is due to Allah who fed me this food and provided it for me, without any power or strength from myself.”
(Musnad Ahmad: 3/439)

In another hadith, it is mentioned that when the Messenger of Allah sallallahu alayhi wa sallam would eat or drink, he would recite the following supplication:
(alhamdu lillahi allathee at‘ama wa saqa, wa sawwaghahu wa ja‘ala lahu makhrajan)
“All praise is due to Allah who fed and gave drink, made it pleasant, and created for it an exit.”
(Sunan Abi Dawud, al-At‘imah, Hadith: 3851)

A well-known supplication after eating is as follows:
(alhamdu lillahi allathee at‘amana wa saqana, wa ja‘alana muslimin)
“All praise is due to Allah who fed us and gave us drink, and made us Muslims.”
(Sunan Abi Dawud, al-At‘imah, Hadith: 3850)

However, this narration is weak.
‘Allamah al-Albani rahimahullah has declared it weak.
(Da‘if al-Jami‘, No: 4436)

Explanation:
1:
All praise is due to Allah alone,
abundant praise,
pure sustenance,
blessed sustenance,
may this not be our last provision from Allah, and O our Lord! may we never be in need of anything apart from it.

Benefits and Issues:
Benefit: (Not self-sufficient.
.
.
etc.) A person, after eating once, again desires it.
He cannot do without it.
Therefore, gratitude for a blessing like food should also be of a similar nature,
which is of great significance.
And this is only possible through the supplications taught by the Noble Prophet (sallallahu alayhi wa sallam).

Benefits and Issues:
➊
The translation of this supplication can also be:
This praise is not considered sufficient (because a human being can never truly praise as is His due),
nor is it abandoned (rather, this praise and gratitude is continuous, because the blessings of the Lord are continuously being received),
nor can there be any independence from this praise (because in order to maintain the blessings already received and to obtain further blessings, the servant is always in need of praise and gratitude).

➋
It is recommended (mustahabb) to recite this supplication at the end of the meal.
