In the name of God, the Most Gracious, the Most Merciful. Where are the other divine books located?

If the intent behind "heavenly books" is the Torah, the Gospel, the Psalms, and the Scrolls of Abraham, then they have been distorted, added to, and subtracted from, and some of them have been lost. What remains is mixed with distortion. The only authentic heavenly book that has not been subjected to distortion today is the Holy Quran, because Allah guaranteed its preservation, saying: "Indeed, it is We who sent down the Dhikr (the Quran), and indeed, We will be its Guardian." And because it is the final book with which Allah sealed the heavenly scriptures, it was imperative to preserve it so that it remains a proof and a miracle.
