Tafsir of Al-Waqi'ah 56:84

(And you), O losers, around him (the one dying), (at that moment), that is, at the time when [the soul] reaches the throat and arrives at it, or when its detachment becomes imminent, (are looking on) (at what he is enduring of the agonies [of death]). It is said: (You are looking on) at your own state; the rationale being that they know what has befallen him will befall them, so it is as if they were witnessing their own condition—though this is not the preferred interpretation.

'Isa recited "hīna-idhin" (at that moment) with a kasra on the nun, following the vowel of the hamza in idh.
