Did the Prophet, may Allah bless him and grant him peace, name all of the Most Beautiful Names of Allah, or did he not name them? And is it permissible to consider "Al-Na'im" (The Bliss) as the name that completes the hundred?

The Most High God's names are not limited to a specific number, and God has reserved knowledge of some of them to Himself. It is stated in the noble hadith that Allah has ninety-nine names, whoever enumerates them will enter Paradise. The Prophet's supplication indicates the multitude of His names: "I ask You by every name belonging to You by which You have named Yourself, or revealed in Your Book, or taught to any of Your creation, or kept hidden in the unseen with You." Scholars have differed regarding the authenticity of the Tirmidhi hadith that lists specific names, and researchers have favored its weakness, as God's names are divinely ordained and it is not permissible to name God through personal inference. Sheikh Ibn Uthaymeen, in "Al-Qawa'id Al-Muthla," collected ninety-nine names that have been authentically mentioned in the Qur'an and Sunnah.
