An entire surah of the Qurʾan bears her name. She is the only woman mentioned by name in the Qurʾan indeed; her name appears more frequently than that of either Muhammad or Jesus. From the earliest times to the present day, Mary has continued to be held in high regard by Christians and Muslims alike. And yet Mary has also been the cause of much rancour and tension between these two world religions. In this groundbreaking study, Muna Tatari and Klaus von Stosch painstakingly reconstruct the picture of Mary that is presented in the Qurʾan and show how veneration of the Blessed Virgin Mary in the Roman Catholic Church intersects and interacts with the testimony of the Qurʾan. Their sensitive and scholarly treatise is an important contribution to constructive interfaith dialogue in the 21st century.
