We know for certain whatever the earth corrodes of them (to the most minute particle); with Us there is a book recording and preserving (incorruptibly)
(But) We know what the earth takes of them. (It is only their physical body that becomes dust. Their "Self" lives on). And with Us is a Guarded Book (of Laws)
We know all that the earth consumes of their bodies, and We have a Book which keeps records of everything
Dr. Munir Munshey
(Really)? We know very well everything that the earth consumes from their (dead decomposing) bodies. With Us is the book that (records and) preserves (every event)
Dr. Kamal Omar
Surely, We knew how much of them the earth consumes, and with Us is a book (of records) which fully preserves (every thing)
We know how much of them the earth consumes (and how much it adds to them). We have with Us a book that preserves (everything - the Law of conservation)
We know exactly what the earth detracts from them (what is lost with old age)... With us is the Book of Records (the universal memory recorded within the essence of existence).
Al-muntakhab fi tafsir al-Qur'an al-Karim
But We Have already and thus early known to what extent has the earth consumed of the corpses of their dead, (or it may be; what the earth shall regularly consume of them by death) We keep a book where everything is related in writing and set down in a permanent form
