Tafsir of Al-Qamar 54:52

Surah Al-Qamar (The Moon): Verse 52

"...And everything they have done..."

This indicates that the matter is not limited to their immediate destruction; rather, the destruction is the swift consequence.

The deferred punishment, which is prepared for them because of what they did, is recorded for them.

"And the Zubur (writings/records)..."

This refers to the books of the scribes, concerning whom the Almighty said:

"Nay, but you deny the Recompense! And indeed, over you are appointed guardians, honorable scribes, who know what you do." (Al-Infitar: 9-11)

And the phrase "...they have done" (fa'alūhu) is an adjective describing "everything" (shay'un), and an indefinite noun can be described by a verbal sentence.
