“Idhā al-samāʾu inshaqqat”
“When the sky is split open.” (al-Inshiqāq 84:1)
“Yā ayyuhā al-insānu innaka kādiḥun ilā rabbika kadḥan fa-mulāqīh”
“O humanity, you are striving toward your Lord, and you shall meet Him.” (84:6)
The chapter opens with a sequence of conditions and cosmic scenes, then turns directly to the human encounter with God. Grammatical analyses differ on how to account for the expected response to “idhā”; the rhetorical purpose is evident from the discourse.
Those events lead to reckoning and recompense. Proposed ellipses clarify the connection but are not wording to insert into the text. The scene and the address must be interpreted as one coherent passage.
