Book of Idols

The Book of Idols (Kitāb al-ʾAṣnām), written by the Arab scholar Hisham ibn al-Kalbi (737–819), is the most popular Islamic work about the religion in pre-Islamic Arabia. Arabian religion before Muhammad is described as polytheistic and idolatrous. Ibn al-Kalbi portrays this state of religion as a degradation from the pure monotheism introduced by Abraham and his son Ishmael, only restored by the coming of Islam. Ibn al-Kalbi relied on Arab oral tradition to write his work. Historians agree that the Book of Idols is not a reliable source for Arabian religion before Islam.
