In what language were the Torah, the Gospel, and the Psalms revealed?

The Torah was revealed in Hebrew and the Gospel in Syriac. As for the Zabur (Psalms), scholars have not mentioned anything regarding its language, but it is likely that it was revealed in one of these two languages, because David, peace be upon him, was from the Children of Israel, and prophets were sent in the language of their people, as Allah Almighty says: "And We did not send any messenger except with the language of his people." There is no benefit in knowing the languages of these books because they have been distorted, and the Quran is sufficient, as in the verse: "Is it not sufficient for them that We revealed to you the Book which is recited to them?" And due to the Prophet's (peace and blessings of Allah be upon him) saying: "Had Musa been among you and you followed him and left me, you would have gone astray."
