Sam'ani writes the following about him: "Hafiz Abu Ahmad Abdullah bin Ali bin Muhammad Gorgani, better known as Ibn Qattan, is the great memorizer of his time. He moved to Alexandria and Samarqand as well as entered many other cities and studied with many teachers. He was a strong and unmatched memorizer. Hamzah bin Yusuf Sahmi says that he asked Daru Qutni to write a book on weak and unreliable narrators and he asked me in return if I did not have Ibn Adi's book. I said that I did.
