Not every verse requires a reconstructed missing word. The express wording is what is recited; a proposed reconstruction (taqdīr) supplies what is understood; and a contextual indicator (qarīnah) makes such reconstruction warranted.
“Wa-sʾal al-qaryah”
“Ask the town.” (Yūsuf 12:82)
In context this means asking the people of the town; buildings cannot answer questions. “The town’s inhabitants” therefore clarifies the sense. Yet the revealed wording remains “ask the town”; the word “inhabitants” is explanatory, not part of the recited verse.
A proposed ellipsis should be no larger than the context requires. Supplying unnecessary words may obscure the expression’s deliberate concision.
