About “Book of Idols”
The Book of Idols, written by the Arab scholar Hisham ibn al-Kalbi, is an Islamic work that describes the religious practices of pre-Islamic Arabia. It presents Arabian religion as polytheistic and idolatrous, portraying this as a decline from the monotheism taught by Abraham and Ishmael, which was restored by Islam. Ibn al-Kalbi based his account on Arab oral traditions. However, many modern historians question the reliability of the book as a source for understanding pre-Islamic Arabian religion.
