Qur’an (to Mohammad via. Gabriel)
Tawrat (Torah of Moses)
Zabur (Book of Psalms)
Zabur (Arabic: زبور) is, according to Islam, the holy book of Dawud (David), one of the holy books revealed by God before the Quran, alongside others such as the Tawrat(Torah) of Musa (Moses) and the Injil (Gospel) of Īsā (Jesus). Some scholars equate the Zabur with the biblical book of Psalms.
Injil (Gospel of Jesus)
Injil (Gospel of Jesus) - Injil (Arabic: إنجيل, translit. ʾInjīl, alternative spellings: Ingil or Injeel) is the Arabic name for the Gospel of Jesus (Isa). This Injil is described by the Qur'an as one of the four Islamic holy books which was revealed by God, the others being the Zabur (possibly the Psalms), the Tawrat (the Torah), and the Qur'an itself. The word Injil is also used in the Quran, the Hadith and early Muslim documents to refer to both a book and revelations made by God to Jesus.
