The Collyridians have become of interest in some recent Christian–Muslim religious discussions in reference to the Islamic concept of the Christian Trinity. The debate hinges on some verses in the Qur'an, primarily 5:73, 5:75, and 5:116 in the sura Al-Ma'ida, which have been taken to imply that Muhammad believed that Christians considered Mary part of the Trinity. This idea has never been part of mainstream Christian doctrine, and is not clearly and unambiguously attested among any ancient Christian group (including the Collyridians).
