Relationship with other literature

The Torah and the Bible
See also: Biblical narratives and the Qur'an and Tawrat
“
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, and He sent down the criterion (of judgment between right and wrong).[96]
”
—Qur'an 3:3 (Yusuf Ali)
The Qur'an speaks well of the relationship it has with former books (the Torah and the Gospel) and attributes their similarities to their unique origin and saying all of them have been revealed by the one God.[97]
The Qur'an retells stories of many of the people and events recounted in Jewish and Christian sacred books (Tanakh, Bible) and devotional literature (Apocrypha, Midrash), although it differs in many details. Adam, Enoch, Noah, Heber, Shelah, Abraham, Lot, Ishmael, Isaac, Jacob, Joseph, Job, Jethro, David, Solomon, Elijah, Elisha, Jonah, Aaron, Moses, Zechariah, John the Baptist, and Jesus are mentioned in the Qur’an as prophets of God (see Prophets of Islam). Muslims believe the common elements or resemblances between the Bible and other Jewish and Christian writings and Islamic dispensations is due to their common divine source, and that the original Christian or Jewish texts were authentic divine revelations given to prophets.
Muslims believe that those texts were neglected, corrupted (tahrif) or altered in time by the Jews and Christians and have been replaced by God's final and perfect revelation, which is the Qur'an.[98]

Influence of Christian apocrypha‎
The Diatessaron, Protoevangelium of James, Infancy Gospel of Thomas, Gospel of Pseudo-Matthew and the Arabic Infancy Gospel are all alleged to have been sources that the author/authors drew on when creating the Qur'an.[99] The Diatessaron, as a gospel harmony, especially may have led to the misconception in the Qur'an that the Christian Gospel is one text.[100] However this is strongly rejected by Muslim scholars, who maintain that the Qur’an is the divine word of God without any interpolation, and the similarities exist only due to the one source.[cit
