Four major revealed scriptures are commonly named:
Tawrat (Torah) — revelation associated with Moses.
Injil (Gospel) — revelation associated with Jesus.
Zabur (Psalms) — revelation associated with David.
Qur'an / Furqan — the final revelation received by Muhammad ﷺ.
Affirming their divine origin does not automatically establish that every later manuscript, version or reported text is identical in its present form to the original revelation. The original revelation and its later transmission are distinct questions.
