Sura 32:23. We did indeed aforetime give the Book (Torah) to Moses: be then NOT IN DOUBT of its (The Torah) reaching (THEE): and We made it a Guide to the Children of Israel.

Sura 10:94. If thou wert in doubt as to what We have revealed unto thee, then ask those who have been reading the Book from before thee (the Bible): the Truth hath indeed come to thee from thy Lord: so be in no way one of those in doubt.
10:95. Nor be of those who reject the Signs of "I AM" (the Bible), or thou shalt be of those who perish.

Idris/Enoch 102:7 Now will I point out a mystery (Revelation 17:5): Many sinners shall turn and transgress against The Word of Uprightness (Isaiah 33:15; 2 Thessalonians 2:7-12; Sura 32:23).
THE INCORRECT WRITING OF GOD'S WORDS PROPHESIED:-
102:8 They shall speak evil things; they shall utter falsehood; create a great creation (false religions and religious traditions and technology); and compose books of their own words (books of man-made laws; books of the religious traditions of their fathers; novels; etc.; etc.; etc.).
HOW TO RECOGNISE AND CORRECT THE MISTAKES:-
But when they shall write correctly all My words in their own languages,
102:9 They shall neither change nor diminish (Mark 13:31; Matthew 5:17-19); but when all shall be written correctly; ALL, which from the first I have uttered concerning them [shall concur] (Sura 15:9).

JAH - Muad'dib.
