The last book is Al-Qur’an, whose custody is under the responsibility of Allah Rabbul Alamin himself. Allah Ta’ala says: ‘Surely it is I who sent down the Qur’an and surely I will preserve it.’ (Sura-15 [54] Hijr, verse: 9). ‘Surely that Qur’an is in the preserved script; No one can touch it except the holy ones. Which is sent down from the Lord of the worlds.’ (Sura-56 [46] Waki’ah, verses: 77-80). Which was incarnated through Hazrat Jibraeel Amin (AS), the most faithful, reliable and powerful angel known as Ruhul Amin. ‘Rather it is the honorable Qur’an; There is a preserved pot.’ (Sura-85 [27] Tower, verses: 21-22).

Muslims believe that the Quran was orally revealed by God to the final prophet, Muhammad, through the archangel Gabriel incrementally over a period of some 23 years, beginning in the month of Ramadan, when Muhammad was 40; and concluding in 632, the year of his death. Muslims regard the Quran as Muhammad’s most important miracle; a proof of his prophethood; and the culmination of a series of divine messages starting with those revealed to Adam, including the Torah, the Psalms and the Gospel. The word Quran occurs some 70 times in the text itself, and other names and words are also said to refer to the Quran.

The Quran is believed by Muslims to be not simply divinely inspired, but the literal word of God. Muhammad did not write it as he did not know how to write. According to tradition, several of Muhammad’s companions served as scribes, recording the revelations. Shortly after the prophet’s death, the Quran was compiled by the companions, who had written down or memorized parts of it.Caliph Uthman established a standard version, now known as the Uthmanic codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning.
