The Rocky Tract and the Guarding of the Revelation

Al-Hijr, 99 Meccan verses, is named for the rock-hewn dwellings of Thamud in northwest Arabia. It recalls destroyed peoples and the guests of Abraham and Lot, and contains the pledge that God Himself sent down the Reminder and will preserve it (15:9), a verse central to Muslim belief in the Quran's integrity.

Al-Hijr's account of Thamud's rock-hewn dwellings, carved into the sandstone cliffs of a site in northwest Arabia identified in the exegetical tradition with Mada'in Salih, situates the surah's warning within a landscape early Muslims could still see for themselves on the trade route to Syria, and reports describe Muhammad instructing his companions traveling through the area not to linger or drink from its wells. The pledge that God will preserve the Reminder (15:9) is treated in Islamic theology as the scriptural basis for the doctrine that the Quran's text has been kept free from the kind of alteration Muslim tradition holds befell earlier scriptures, a claim classical commentators including al-Tabari connect to the meticulous practices of memorisation and written transmission that accompanied the Quran from its earliest recitation. The surah's brief account of Iblis' expulsion for refusing to bow to Adam (15:28-35) closely parallels the fuller version in Al-Araf, part of a Quranic pattern of retelling the same episode with varying emphasis across different surahs.
