During one period of Turkish history, Bediuzzaman Said Nursi was misunderstood by the government and was forced to spend twenty-eight years in exile, driven from place to place and from prison to prison. Thereby he referred to prison as a school of Prophet Joseph (Medrese-i Yusufiyye). This booklet, which we are publishing in the hope that it will be of benefit to the people of the present, is a selection of the letters he wrote to his fellow-prisoners during the course of this unmerited treatment. (Pocket Series) - 38 pages. Paperback.
