Is "Al-Tayyib" among the names of Allah?

"Al-Tayyib" (The Good/Pure) is one of Allah's names mentioned in the Hadith, such as the Prophet's (peace be upon him) saying: "Indeed, Allah is Tayyib (Good/Pure) and accepts only that which is Tayyib." There are also names of Allah that He has kept exclusively in the knowledge of the unseen, neither revealing them in a book nor teaching them to any of His creation, as indicated by the Hadith of the supplication.
