Jahm bin Safwan

Jahm was born in Samarkand, either of Persian ancestry or a non-Persian client of the Banu Rāseb tribe but settled down in Khorāsān specifically Merv. He learned under al-Ja'd b. Dirham. Ja'd b. Dirham was a teacher of the last Umayyad caliph, Marwan II, and is described as a Dahrī and Zindīq (heretic) for being the first person to state that God does not speak, hence the Quran is created. He was the first Muslim reported to have spoken about the createdness of the Qurʾān and reject Abraham's friendship with God and Moses' speaking to Him. The name of Jahm b. Ṣafwān would later be ascribed - possibly spuriously - to the theological movement known as Jahmism. Jahm worked as the assistant to al-Harith ibn Surayj during the latter's revolt against the Umayyad governor Nasr ibn Sayyar. Jahm was killed during the first attempt to take Merv in 746, though the revolt greatly weakened Umayyad power and indirectly contributed to the success of the Abbasid Revolution. ==Teachings==

Establishing the positive content of Jahm's doctrines is difficult, as they are reproduced (in an abbreviated form) only in later polemical works that are impossible to verify. However, it is said that he taught that only a few attributes can be predicated to God, such as creation, divine power and action, whilst others such as speech cannot. Therefore, he believed that it was wrong to talk about the eternal word of the Qur'an, since God (according to Jahm) is not a speaker in the first place. Jahm was a proponent of extreme determinism, according to which a man acts only metaphorically in the same way in which the sun is said to set: according to Jahm, this is a linguistic convention rather than an accurate description, as it is actually God that makes the sun set. ==Legacy==

Jahm's doctrines about God and the attributes of God were taken up in criticisms of the Mu'tazila, who were sometimes called Jahmites by their adversaries. The Mu'tazila believed that the Qur'ān was created, a tenet which agreed with Jahm's recorded view. Jahm left no writings, but many Muslim scholars wrote about his doctrines and a few modern scholars have written studies of him. ==Criticism==

Contemporaries Muqatil ibn Sulayman, an early commentator on the Qur'an who Sunni Muslims view as the polar opposite of Jahm, who went to the other extreme, was a contemporary of Jahm who was particularly critical of him. Between the two men, a heated theological and political debate took place in the mosque of Marw regarding the divine attributes and two political figures with whom both men were affiliated. Each of them ended up writing a book refuting the other, and Muqatil used his political links to get Jahm expelled from Balkh, having him sent to Termez. Abu Hanifah (d. 150 H) also harshly criticised Jahm, and this was alongside his criticism of the opposing Muqatiliyyah. In particular, Abu Hanifah went as far as declaring Jahm a disbeliever. Later scholars A theologian by the name of Uthman bin Sa'id ad-Darimi (d. 280 H) (not to be confused with al-Darimi, the author of the Sunan al-Darimi) also wrote refutations of Jahm and wrote an extensive refutation of a prominent Jahmite by the name of Bishr al-Marisi wherein he declared him a Kafir (a disbeliever). In particular, the Sunni Hadith scholar and ascetic al-Hakim al-Tirmidhi (d. ~280 H) wrote a response to him. Many Hadith scholars wrote refutations of Jahm bin Ṣafwān's doctrines, notably the Sunni Hadith scholar Ahmad ibn Hanbal (d. 241 H) and his students like al-Bukhari (d. 256 H) and Abu Dawud as-Sijistani (d. 275 H). Al-Bukhari adopted the teachings of the traditionalist and scholar of Kalam Ibn Kullab alongside al-Karabisi in matters of creed, who also repudiated the Jahmiyyah. Then, later Sunni Kalam theologians continued to criticise him, in particular Abu Hasan al-Ash'ari (d. 324 H) and Abu Mansur al-Maturidi (d. 333 H), and he continued to be mentioned in later Ash'ari and Maturidi heresiology works. ==See also==
