لَتَرَوُنَّ الْجَحِيمَ
You shall certainly see the blazing Fire. (التكاثر: 6)
La-tarawunna combines an emphatic lām with the heavy nūn of emphasis. Earlier the audience was told it would come to know; now it is told it will see the Fire. Al-jaḥīm is the stated object of the verb, and the shift from future awareness to sight intensifies the warning.
The form is not an imperative or a description of a present circumstance. It is an emphatic report of a future encounter. Its emphasis must be interpreted with the passage’s threatening context, where it underlines the certainty of what is announced.
