It is written in the (Muqadma) Preface on pages 6-7 of the above-mentioned book: -

"Circumstances Around the Revelation, Collection and Compilation of the Quran Majeed"

Conclusion of the article written by the author in the Preface of the aforesaid book Quran Majeed on pages 6-7: -

The Quran Majeed (Sharif) was completely written in 23 years. It started when Hazrat Muhammad was 40 years old and continued for 23 years until his final age of 63 years. Sometimes one verse, sometimes half, sometimes two verses, sometimes 10 verses, and sometimes the entire Surats were revealed. This is called "Wahy" in Shariat.

Scholars have written that different methods of “Wahy” (revelations) have been mentioned in the hadith.

When the angel used to bring "Wahy (revelation)", the bells used to ring. Prophet Muhammad used to feel as if he was about to die. This method used to be the most troublesome for Prophet Muhammad. This is also written that after Hazrat Muhammad’s prophethood (from the age of forty, after becoming a prophet) in the days of Ramadan, the entire Quran Majeed (Sharif) was revealed from Allah, by the order of Allah (Lord), from the sky which we cannot see, that is, it was spoken by that Allah alone. After this, whenever and whatever order Hazrat Jibreel received, he conveyed the Holy Kalam exactly like that to Prophet Muhammad without any changes.
Sometimes the angel used to convey some message into his heart.
The angel used to come in the form of a man and talk to him.

(Note- It is written in the biography of Hazrat Muhammad ji that when Angel Jibreel brought the revelation the first time, he was visible in a human form. He strangled Muhammad ji and said, “Read it.” Hazrat Muhammad ji described, “I felt as if he was strangling me and pressing my body. He did this twice and then again said for the third time, “Read it.” I felt that he would strangle me again; this time he would squeeze me harder, I said, “What should I read?” He taught me the first verse of the Quran, I memorised it. Then the angel went away; I was terrified. My heart was sinking. The whole body started trembling. After coming out of the cave, I thought “Who was this?” Then the same angel became visible in the form of a man. He was visible wherever I looked. Up, down, right, left, in all directions. I came back home and lay down covering myself with a sheet. My whole body was drenched in sweat. “Khadija! I am afraid that I might die.” Then Hazrat Muhammad ji narrated the entire incident to his wife Khadija. Then a person named 'Baraka' on hearing the entire incident from Hazrat Muhammad ji said, “You will become a 'Prophet'. The same angel also used to come to Musa ji.” The above description proves that although the angel brought the revelation in the form of a man, Hazrat Muhammad ji used to suffer a lot.}

Allah directly used to convey (Kalaam) message to Prophet Muhammad (Sallal) while he was awake. The meaning is that Brahm himself used to speak through an ethervoice.
Allah used to convey the (Kalaam) message in the dream.
The angel used to come in the dream and convey message (There is a dispute over this fifth and sixth type; the rest of the above-mentioned 4 methods of revelation of Quran Majeed (Sharif) are correct.) It is written on page 29 that sometimes "Wahy (revelation)" used to come by itself. The meaning is that just as a ghost possesses someone and speaks. Sometimes, Prophet Muhammad used to lie down and cover himself with a sheet, then he used to speak from inside the sheet.

It is clear from the article written in the Preface of the Holy Quran Majeed (Sharif) on pages 6-7 that the knowledge of the Quran has been given by the Allah, who stays behind the curtain. The Angel named Jibreel has only served as a messenger. The Giver of knowledge of the Quran describes the glory of the (Kaadir) Almighty Allah, the Creator of the universe, other than himself. He describes his own too.
