Bismillaahir Rahmaanir Raheem
Assalamu Alaikum wa Rahmatullahi wa Barkatuh!
Anas bin Malik (May Allah be pleased with him) reported:
The Messenger of Allah (Sall-Allahu alayhi wa sallam) said,
"ALLAH, Subhanahu wa Ta'ala,
will be pleased with His slave
who praises Him
(i.e., says Al-hamdu lillah)
when he eats
and praises Him when he drinks".
[Muslim].
Commentary:
If a person expresses his gratitude
to Allah Subhanahu wa ta'ala, for food,
which besides being a source of nourishment
is enjoyable for him,
he gets a reward for it and thus
even eating can become rewardable too.
