The Qur'an relates detailed narrative accounts of Maryam (Mary) in two places, Qur'an 3:35–47 and 19:16–34. These state beliefs in both the Immaculate Conception of Mary and the Virgin birth of Jesus. The account given in Sura 19 is nearly identical with that in the Gospel according to Luke, and both of these (Luke, Sura 19) begin with an account of the visitation of an angel upon Zakariya (Zecharias) and Good News of the birth of Yahya (John), followed by the account of the annunciation. It mentions how Mary was informed by an angel that she would become the mother of Jesus through the actions of God alone.
