What is the best book explaining the beautiful names of Allah?

Question:
I ask Allah for you. Your Eminence, father, the questioner asks: What is the best book explaining the beautiful names of Allah the Exalted?

Answer:
There are many explanations in tafsir (exegesis). Follow them in the tafsir, and you will find that the mufassirun (exegetes) have explained them. However, collecting them in a book and explaining them is first of all incalculable. The names of Allah are incalculable in a book; the names of Allah are many. But the ninety-nine names that the Messenger (peace and blessings be upon him) specified by saying, “Indeed, Allah has ninety-nine names, whoever enumerates them will enter Paradise,” these are the ones that can be tracked. Track them from the Qur'an and the Sunnah until you reach ninety-nine. A group of scholars have tracked them, recorded them, explained them, and composed them in poetry. They are found in the al-Nuniyyah by Ibn al-Qayyim. They are found in explanations of the beautiful names from old and new books under the title “Explanation of the Beautiful Names.” As for what is in al-Tirmidhi, “Indeed, Allah has ninety-nine names,” and he mentioned these ninety-nine names at the end, this is inserted into the hadith counting them. This is an insertion by some of the narrators. Yes.
