Book of Idols

The Book of Idols (Kitāb al-Așnām), written by the Arab scholar Hisham Ibn Al-Kalbi (737–819), describes gods and rites of Arab religion. The text is critical of pre-Islamic religion and decries the state of religious corruption which the Arabs had supposedly descended to since the founding of the Kaaba. The book was instrumental in identifying shirk (the sin of polytheism) with "the idolatry of the pre-Islamic Arabs."

Ahmad Zaki Pasha, the Egyptian philologist, discovered the text; he bought the sole extant manuscript at auction in Damascus and the manuscript, one of many in his extensive collection, was donated to the state after his death in 1934. Zaki Pasha announced his discovery at the XIVth International Congress of Orientalists.
