Surah 15. Al-Hijr, Ayah 80

I.e., the tribe of Thamud (see surah {7}, note [56]), who in pre-Islamic times inhabited the region of Al-Hijr in northernmost Hijaz, south of the oasis of Taymah. The story of the Thamud is found in {7:73-79}.

 lit., messengers, because denying Ṣâliḥ (ﷺ) was equal to denying all of Allah’s messengers.

"The Rocky Tract" is undoubtedly a geographical name. On the maps of Arabia will be found a tract called the Hijr, north of Medinah, Jabal Hijr is about 150 miles north of Madinah. The tract would fall on the highway to Syria. This was the country of the Thamud. For them and the country see vii. 73, n. 1043.
