And His statement ( We already know what the earth takes away from them ) (50:4). The Exalted, whose praise is mentioned, says: We already know what the earth consumes of their bodies after their death, and with Us is a book concerning what the earth consumes and decomposes of their bodies; and they have, in addition to Our knowledge thereof, a recorded book that preserves all of this. And Allah, the Exalted, has called it "preserving" (ḥafīẓ), because what is written in it does not fade, does not change, and is not replaced.
And in accordance with what we have said about this, the people of interpretation (ahl al-taʾwīl) have spoken.
