What Shahrur Says
The witness attributed to Shahrur states: “The Qur’an confirms some of what is in the earlier books.” The qualification of confirmation by “some” is an explicit part of the claim.
Atlas Explanation
On the basis of this statement, the claim must not be formulated as a comprehensive confirmation of the earlier books, because the word “some” limits the scope of the claim. The issue is connected to the context of reading stories and earlier books in Muhammad Shahrur, The Qur’anic Stories, Vol. 1, and to the entry the Book, the Qur’an, and the Mother of the Book.
Conclusion
The limited editorial conclusion is that the confirmation in this atom is partial, not total.
Open Question and Limits of the Evidence
The available witness does not provide a criterion for determining what falls within the “some” that is confirmed, nor does it state how the rest should be described or handled. Therefore, no further details about “remnants of truth” or “review and distinction” should be attributed to Shahrur here without a more explicit witness.
