﴿وَلَوْ تَرَى إِذْ وُقِفُوا عَلَى النَّارِ﴾
If only you could see when they are made to stand before the Fire. (Al-Anʿām 6:27)
The condition introduced by law is stated, but its consequence is not. A possible explanatory expansion is la-raʾayta amran ʿaẓīman, “you would see an overwhelming sight,” yet the omitted wording need not be confined to one formulation.
The open-ended ellipsis invites the mind to contemplate the gravity of the scene. Its effect is expressive, not merely economical.
