15. Surah Al-Hijr (The Rocky Tract / The Stone Land) is the 15th chapter of the Quran, containing 99 verses. It derives its name from Verse 80, which mentions the “Companions of Al-Hijr”—the ancient civilization of Thamud who carved their homes directly into the mountains. This chapter serves as a stark warning to the deniers of truth and a profound psychological source of comfort for the Prophet Muhammad ﷺ during his hardest trials.
