Thabr
In Islamic demonology, Thabr is one of the five sons of Iblis mentioned in Quranic commentary on Surah 18:51, which speaks about the offspring of Iblis. The devil is further mentioned in a hadith by Muslim ibn al-Hajjaj. He is a devil who causes calamities and injuries. His four brothers are named: Awar, Zalambur, Sut, and Dasim. Each of them is linked to another psychological function, which they try to encourage to prevent humans spiritual development.
