The Holy Qur'an (also known as The Koran) is the sacred book of Islam. For Muslims, it is the word of the one God. The Qur'an was revealed to the last prophet and messenger Muḥammad (محمد) from the year 610 until his death in 632 by the angel Gabriel (جبريل).
According to the Qur'an, God exists and is unique, and He is the author of all the sacred books of the three monotheistic religions that are Islam, Christianity, and Judaism. He thus revealed the Gospel to the penultimate prophet Jesus and the Torah to the prophet Moses. We read thus in verse 3 of sura 3: "It is He Who sent down to thee (step by step), in truth, the Book, confirming what went before it; and He sent down the Law (of Moses) and the Gospel (of Jesus) before this, as a guide to mankind".
