Bayan ibn Saman al-Tamimi

Bayān ibn Samʿān at-Tamīmī an-Nāhdī (Arabic: بيان بن سمعان التميمي النهدي) was the founder of the 8th-century Bayaniyya sect of Shi'a Islam, as well as a claimant to prophethood. He was also the first to spread the idea of Quranic createdness.

Teachings According to the Shi'ite theologian Abu Muhammad al-Hasan ibn Musa al-Nawbakhti, Bayan ibn Sam'an was a Shi'ite of the Ghulat who supported Abu Hashim as a rightful caliph, but later claimed prophethood after Abu Hashim died. Bayan ibn Sam'an was also a supporter of the idea of Quranic createdness and was considered as one of the first people to have propagated the idea widely. These theological virtues regarding the Qur'an served as the basis for the theology of al-Ja'd ibn Dirham and later Jahm ibn Safwan of the Jahmi group.

Death Bayan ibn Sam'an was executed for his beliefs, which the majority of the Muslim scholars considered to be heretical at the time.
