In the Hereafter, a denier's own ears, eyes, and skin will be commanded to testify against them. This vivid warning anchors a Makkan defense against polytheists who campaigned to discredit the Quran as an invention. Named Fuṣṣilat (Clearly Detailed) from its third ayah, the chapter has also been called al-Maṣābīḥ (The Lamps) and al-Aqwāt (The Provisions) based on specific verses. It is also known as Ḥā-Mīm al-Sajdah, marking its opening letters and verse of prostration.

The text opens by asserting the Quran's freedom from falsehood, challenging those who claim fabrication without having received a prior revelation. The argument grounds monotheism in the creation of the heavens, earth, and its sustenance, then shifts to warnings about the destroyed nations of ʿĀd and Thamūd.

Past the stark scene of bodily betrayal at Judgment and the deceit of earthly partners, the tone pivots to immense consolation. Angels descend to assure believers of their safety, before the final verses cement the reality of the Resurrection, leaving the time of the Hour entirely to Allah.
