Is the Verse of Isaiah 29:11 about Prophet Muhammad?
Muslims believe that the verse Isaiah 29:11
is about the Koran and Prophet Muhammad. They argue that if this is true then the book sealed has already been opened by Prophet Muhammad, and so Maitreya is incorrect and his claim is false since the sealed book is opened already and Prophet Muhammad was the last Prophet.
The answer is that they are half correct. Yes indeed, that verse is Revealed for Prophet Muhammad and the Revelation He received. He was offered to read (Koran) and He could not since He was illiterate. However, as you can see it says the "book that is sealed," not the Book Sealed with the Seven Seals.
In fact all Scriptures (books) Revealed by Major Prophets were Sealed and unknown to humans until they were Revealed to man. So all of them opened a sealed book and One of the Seals of the Seven Seals. The Book which Reveals the Mystery of all the Revelations (Seals) before it is the Book Sealed with the Seven Seals that will Reveal the meaning of each Seal (book sealed) in the Plan of God.
This last Revelation of God will be Revealed with One who has Fulfilled all the Prophesies, is the Lion of the Tribe of Judah, a Sayyed, etc, etc. This only will happen at the End Time. This later Revelation is what Maitreya Claims He has opened. Prophet Muhammad could not have been this Last Prophet and Revealer. This Muslims and all humanity have to understand and Surrender unto.
