This is the first volume of Goldihers Muslim Studies, which ranks highly among the classics of the scholarly literature on Islam. Indeed, the two volumes, originally published in German in 1889-1890, can justly be counted among those that laid the foundations of the modern study of Islam as a religion and a civiliation. This volume, with the authors marvelous richness of information, profound historical sense, and sympathetic insight into the motive forces of religion and civiliation, is today as fresh as at the time of its original publication.
