إِذَا السَّمَاءُ انْشَقَّتْ ۞ وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ ۞ وَإِذَا الْأَرْضُ مُدَّتْ ۞ وَأَلْقَتْ مَا فِيهَا وَتَخَلَّتْ ۞ وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ
When the sky is split and heeds its Lord, as it rightly must, and when the earth is stretched, empties its contents, and obeys its Lord. (84:1–5)
Like the opening of al-Infiṭār, these verses use idhā. An important difference is that, in well-attested grammatical accounts, the result is understood rather than explicitly stated. The audience imagines the consequence; the later reference to human reckoning points toward its significance.
The repeated “wa-adhinat li-rabbihā wa-ḥuqqat” stresses the common submission of sky and earth. Repetition is not automatically padding: its rhetorical benefit here is the shared obedience of the two vast realms.
