Explanation of the author's statement: "And what He described Himself with in the greatest verse of His Book"

The Shaykh :"And what He described Himself with" — what is this conjoined to? It is conjoined to the "what" in His statement: "What He described Himself with" in Surat al-Ikhlas.
"And what He described Himself with in the greatest verse of the Book of Allah, yes, in His Book" — may Allah have mercy on you — "In the greatest verse of His Book, where He says" ... to the end of it. This verse is called the Verse of the Throne, because it mentions the Throne and it is the greatest verse in the Book of Allah.
The evidence for this is that the Prophet (peace and blessings be upon him) asked Ubayy ibn Ka'b, saying: أي آية في كتاب الله أعظم ؟ فقال له : اللَّهُ لا إِلَهَ إِلاّ هُوَ الْحَيُّ الْقَيُّومُ فضرب على صدره، وقال : ليهنك العلم أبا المنذر أو قال يا أيا المنذر Which verse in the Book of Allah is the greatest? He said to him: "Allah, there is no deity except Him, the Ever-Living, the Sustainer." He struck his chest and said: "May knowledge bring you joy, O Abu al-Mundhir," or he said, "O Abu al-Mundhir." This means that the Prophet (peace and blessings be upon him) affirmed that this is the greatest verse in the Book of Allah, and that this is proof of Ubayy's knowledge of the Book of Allah, Mighty and Majestic.
Based on this hadith, we understand that the Qur'an differs in rank, as is also indicated by the hadith of Surat al-Ikhlas, which shows that the Qur'an differs in rank. This is a point that requires detail. We say: As for the One who speaks it, it does not differ in rank, because the One who speaks it is One, namely Allah, Mighty and Majestic.
As for its meanings and subjects, it undoubtedly differs in rank. Surat al-Ikhlas, which contains praise of Allah, Mighty and Majestic, through the names and attributes it includes, is not like Surat , which describes the state of that man. In terms of subject matter, not in terms of the Speaker. The Speaker of "He is Allah, the One" is the same as the Speaker of "May the hands of Abi Lahab be destroyed." In terms of the Speaker, there is no difference in rank. But undoubtedly, in terms of subject matter, there is a difference. Likewise, there is a difference in impact and strength of style. Some verses are short, yet they contain a strong deterrent for the heart and a lesson. You may find another verse much longer, but it does not contain what the first one contains. For example, His saying, the Exalted: ... to the end of it. This verse has a simple subject matter, and the discussion in it concerns transactions that occur among people. Yes, it does not have that impact which it has in His saying, the Exalted: This carries great meanings, containing prohibition, admonition, encouragement, and warning. It is not like the verse of debt, for example, even though the verse of debt is longer than it. In any case, the difference in rank of the Qur'an in terms of the Speaker is impossible, because the Speaker is One, namely Allah. But in terms of subject matter, meaning, and impact, that differs. Therefore, the Messenger (peace and blessings be upon him) said: He affirmed Ubayy ibn Ka'b in that. And Surat al-Fatihah is the greatest surah in the Book of Allah, and it is the seven repeated verses.
