[Pooya/Ali Commentary 15:80] Refer to the commentary of Araf: 73 to 79 for the people of Thamud and prophet Salih. The dwellers of hijr were the Thamud the people of Salih. They lived in houses that had been hewed out in the mountains. Jabl Hijr is about 150 miles from Madina. The rocky tract of land known by this name lies in the north of Arabia on the highway to Syria.

He who granted the glorious Qur’an, if he thinks others have better bounties than him, has depreciated what God has appreciated. He, who has not regarded for self, for being obedient to God, shall die in grief and sadness. He, who shall look at other’s property, will be seized by grief, intensity of which will not leave him. He, who does not appreciate Divine bounty, except in food and drink, failed in virtues. He, who started morning in anxiety, shall displease God. He, who complains of adversity, has complained against God. He, who stretches his hand to the rich for money, has lost two-thirds of his faith. If any of the Muslims, after reading the Qur’an, is condemned to Hell, is as though her played with it (i.e. did not put the commands of the Qur’an into action).
