وَاسْأَلِ الْقَرْيَةَ
And ask the town. (Qurʾān 12:82)
On a well-known elliptical reading, the intended respondents are the town’s inhabitants. This is a strong case for discussing deletion because the act of questioning requires people able to provide testimony, not buildings. The contextual clue makes the intended reference recoverable.
By contrast, reconstructing extra words in a sentence already grammatical and sufficiently clear can manufacture an ellipsis. The right question is: what evidence licenses this particular reconstruction, and does the sense actually require it?
