Concise Quran Commentary
Indeed the Thamud, who were the people of Hijr (a place between Hijaz and the Levant) had in effect rejected all the Messengers when they rejected their prophet, Salih (peace be with him.)
وَلَقَدْ كَذَّبَ أَصْحَـٰبُ ٱلْحِجْرِ ٱلْمُرْسَلِينَ
Surely the people of Al-Hijr[40] also rejected the messengers.
