Islamic holy books are the texts which Muslims believe were authored by God to various prophets throughout humanity's history. All these books, in Muslim belief, promulgated the code and laws that God ordained for those people.
Muslims believe the Quran to be the final revelation of God to man, and a completion and confirmation of previous scriptures.[1] Despite the primacy that Muslims place upon the Quran as God's final word, Islam speaks of respecting all the previous scriptures, and belief in all the revealed books is an article of faith in Islam.
Among the books considered to be revealed, the four mentioned by name in the Quran are the Tawrat revealed to Moses, the Zabur revealed to Dawud, the Injil revealed to Jesus, and the Quran revealed to Muhammad.
