Three openings illustrate vivid, concentrated presentation of the Last Day:
إِذَا الشَّمْسُ كُوِّرَتْ
When the sun is folded up.
إِذَا السَّمَاءُ انْفَطَرَتْ
When the sky is split open.
إِذَا السَّمَاءُ انْشَقَّتْ
When the sky is rent asunder.
These are the openings of al-Takwīr 81:1, al-Infiṭār 82:1, and al-Inshiqāq 84:1. Their expressions and sequences vary, yet each makes the reality of the Resurrection unusually immediate and calls the reader to readiness for the hereafter.
