[3] Jahm and those associated with his theological creed appear as prominent heretics in Sunni heresiography, and to be called a Jahmi became an insult or polemic,[4] especially with respect to proponents of Ash'arism, who were called Jahmiyya on account of the accusation of fatalism and denial of God's attributes by Ibn Taymiyya and his followers, positions they say originated with Jahm.
[10] Another famous preacher of Jahmi views was Bishr al-Marisi (d. 833), at the beginning of the 9th century, Jahmites acted in Nehavend, but some of them were forced to accept the teachings of the Asharites.
For example, Ahmad ibn Hanbal composed a treatise titled the al-Radd ʿalā al-zanādiqa wa-l-jahmiyya ("Refutation of the heretics and the Jahmiyya").
[18] Yasir Qadhi wrote a lengthy dissertation (in Arabic) entitled "The Theological Opinions of Jahm b. Ṣafwān and Their Effects on the Other Islamic Sects.
[21] Ibn Taymiyyah accused Ash'aris of having adopted doctrines of the Jahmiyya and instead advocated for a theology based on what he considered as returning to the views of the Salaf as-Salihin (the first three generations of Muslims).
[5] In later periods, Wahhabis also adopted the term as a derogatory reference to practitioners of Kalam theology, in order to contumely suggest that they, like Jahm, denied God's attributes.
[7] In particular, this accusation was used by early Wahhabis against Maliki Muslims living in eastern Arabia, sometimes singled out as being located in Dubai and Abu Dhabi, who they believed to interpret some of the attributes of God in a purely metaphorical sense.
