Herein, Ibn Rushd I (d. 520/1126) reviews the prohibition of cross-confessional testimony. He clarifies that cross-confessional testimony is specifically forbidden between Christian and Jews, due to the historical presence of enmity between the groups, but is generally permissible in other cases such as among Zoroastrians. In Justice and Leadership in Early Islamic Courts, Ahmed El Shamsy surveys Ibn Rushd as a springboard to discussing the admissibility of testimony which might be prohibited on a case-by-case basis if enmity is known to exist.
