‘Ali (رضي الله عنه) on Alhamdulillah
Hafs mentioned that `Umar (رضي الله عنه) said to `Ali (رضي الله عنه) , “We know La ilaha illallah, Subhan Allah and Allahu Akbar. What about Al-Hamdu Lillah” `Ali (رضي الله عنه) said, “A statement that Allah liked for Himself, was pleased with for Himself and He likes that it be repeated.”
Ibn `Abbas (رضي الله عنه) 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.
