“The science of letters that I possess contains the knowledge of all that is to come, to the end of the world.”
— Jafar al-Sadiq[apocryphal] Attributed to Ja'far in later esoteric literature on the science of letters (ilm al-jafr); not in early Imami collections
Commentary
This claim belongs to the esoteric literature on the science of letters, ilm al-jafr, a body of divinatory and cosmological writing that bears Ja'far's name. The science was thought to reveal the future through the numerical values of letters, and it was taken up by later Shi'i, Sufi, and Ismaili writers. Heinz Halm, in Die Schia (1988), explains that the attribution to Ja'far of such works reflects their later prestige rather than their composition in his lifetime. Wilferd Madelung has discussed the reception of the ilm al-jafr in medieval Islamic thought, noting that its claims were disputed by jurists and theologians. Hossein Modarressi's historical study cautions against accepting attributions to Ja'far of esoteric material that does not appear in the early collections. Marshall Hodgson places the esoteric literature within the broader intellectual culture of the Abbasid period. The statement is an apocryphal attribution and is recorded for its place in the later tradition.
