I want to know the answer to the following question:
Which term used in the Quran to indicate itself means "book"?
All the background I'm provided with is that "In the large majority of contexts, usually with a definite article (al-), the word is referred to as the "revelation" (waḥy), that which has been "sent down" (tanzīl) at intervals.". Is that enough to answer the question?
Answer: no
