The people of the Wood, or al-Aykah, refers to the community of Shu‘ayb. The real name of this community was ‘Banu Madyan’ (the children of Madyan). These people were settled in the area presently known as Tabuk. The people of Hijr refers to the community of Thamud to whom Salih was sent as a prophet. This area was located to the north of Madinah. The arrogance of the people of al-Aykah not only made them polytheists but also pushed them into committing the worst moral crimes. When, in spite of Shu‘ayb’s admonition, they did not mend their ways, God commanded the earth. Thereafter, the earth which had been a cradle of comfort and luxury for them became a cradle of punishment. The community of Thamud were experts in the art of stone-carving. They had cut into the hills and had turned them into lovely dwellings. They thought that they had made complete provision for their safety. When they ignored the call of God, He gave a command and their magnificent dwellings turned into magnificent graves.
