Hafs mentioned that `Umar said to `Ali,
"We know La ilaha illallah, Subhan Allah and Allahu Akbar.
What about Al-Hamdu Lillah?''
`Ali said, "A statement that Allah liked for Himself, was pleased with for Himself and He likes that it be repeated.''
Also, Ibn `Abbas said, "Al-Hamdu Lillah is the statement of appreciation.
When the servant says Al-Hamdu Lillah, Allah says, `My servant has praised Me.''
Ibn Abi Hatim recorded this Hadith
At-Tabari 1:13
