English: The Holy Quran has been revealed to the Holy Prophet in parts during 23 years, from the revelation to the death of the Holy Prophet (PBUH), and he recited and taught the noble verses.

Most Muslims memorized the verses of the Qur'an, and some wrote and preserved the verses with the tools of the day. "Revelation" became known, whose names and biographies are recorded in the history books of Islam.

Then, in stages, verses and chapters of the Qur'an were collected and compiled and became a codified book which was called "Mus'haf" and people copied from this Mus'haf. For further study on this subject, refer to the book See the history of the Qur'an.
