Brethren of Purity

A suggestion made by Ignác Goldziher, and later written about by Philip Khuri Hitti in his History of the Arabs, is that the name is taken from a story in Kalilah waDimnah, in which a group of animals, by acting as faithful friends (ikhwān aṣ-ṣafāʾ), escape the snares of the hunter.

In one passage they give as their reason for hiding their secrets from the people, not a fear of earthly violence, but a desire to protect their God-given gifts from the world (rasā'il 4, p. 166).

Yet they were well aware that their esoteric teachings might provoke unrest, and the various calamities suffered by the successors of the Prophet may have seemed good reason to remain hidden.

[15] According to Palestinian historian Abdul Latif Tibawi, the Encyclopedia contains a passage that states that if an ideal Imam dies, then the community can still be governed by consensus (ijma), which is a Sunni concept.

As evident from The Case of the Animals versus Man, spiritual entities frequently acknowledged by Muslim beliefs, such as angels, jinn, and spirits, function as figures representing Platonic intellects, showing further resemblance to the Mu'tazilite cosmology.

[16] Among the Isma'ili groups and missionaries who favored the Encyclopedia, authorship was sometimes ascribed to one or another "Hidden Imam"; this theory is recounted in al-Qifti's biographical compendium of philosophers and doctors, the "Chronicle of the Learned" (Akhbār al-Hukamā or Tabaqāt-al-Hukamā).

Ian Richard Netton writes that: "The Ikhwan's concepts of exegesis of both Quran and Islamic tradition were tinged with the esoterism of the Ismailis.

[citation needed] Among the Yemenite traces, the earliest reference of the Epistles is found in the fragments of "Sirat Ibn Hawshab" by Ja'far ibn Mansur al-Yaman, who writes: "He (Imam Wafi Ahmed) 8th Imam of Ismaili sect went through many a difficulty and fear and the destruction of his family, whose description cannot be lengthier, until he issued (ansa'a) the Epistles and was contacted by a man called Abu Gafir from among his dais.

This source not only asserts the connection of the Epistles with the Ismailis, but also indicates that the Imam himself was not the sole author (sahibor mu'allif), but only the issuer or presenter (al-munsi).

The other Yemenite source connecting the Epistles with the Ismailis was the writing of the Tayyibi Isma'ili Da'i al-Mutlaq Ibrahim ibn al-Husayn al-Hamidi (d. 557/1162), who wrote Kanz al-Walad.

Apparently, al-Tawhīdī was close to Zaid ibn Rifa'a, praising his intellect, ability and deep knowledge – indeed, he had dedicated his Kitāb as-Sadiq wa 'l-Sadaqa to Zaid – but he was disappointed that Zaid was not orthodox or consistent in his beliefs, and that he was, as Samuel Miklos Stern puts it, ...frequenting the society of the heretical authors of the Rasa'il Ikhwan as-Safa, whose names are also recorded as follows: Abu Sulaiman Muhammed b. Ma'shar al-Bisti al-Maqdisi, Abu'l-Hasan 'Ali b. Harun az-Zanjani and Abu Ahmad al-Mihrajani, and al-'Aufi.

Stern derives a further result from the published text of the Kitāb al-Imtā wa 'l-Mu'anasa, pointing out that a story al-Tawhīdī ascribes to a personal meeting with Qadi Abu'l-Hasan 'Alī b. Hārūn az-Zanjāni, the founder of the group, appears in almost identical form in one of the epistles.

[29]The last contemporary source comes from the surviving portions of the Kitāb Siwan al-Hikma (c. 950) by Abu Sulaiman al-Mantiqi (al-Tawhīdī's teacher; 912–985),[30] which was a sort of compendium of biographies; al-Mantiqi is primarily interested in the Brethren's literary techniques of using parables and stories, and so he says only this little before proceeding to give some extracts of the Encyclopedia: Abū Sulaimān al-Maqdisī: He is the author of the fifty-two Epistles inscribed The Epistles of the Sincere Brethren; all of them are full with Ethics and the science of...

"[32] He explains the al-Tawhidi narrative as being motivated by contemporary politics and issues of hereticism relating to the Qarmatians, and points out that there is proof that Abu Hayyan has fabricated other messages and information.

The fourth part deals with theology in eleven epistles, investigating the varieties of religious sects, the virtue of the companionship of the Brethren of Purity, the properties of genuine belief, the nature of the Divine Law, the species of politics, and the essence of magic.

They define a 'perfect man' in the Encyclopedia: of East Persian derivation, of Arabic faith, of Iraqi, that is Babylonian, in education, Hebrew in astuteness, a disciple of Christ in conduct, as pious as a Syrian monk, a Greek in natural sciences, an Indian in the interpretation of mysteries and, above all a Sufi or a mystic in his whole spiritual outlook.
