TheRisale-i Nur Collection is full of "general principles," not only related to the Islamic Jurisprudence but also to all the fields of Islam or Islamic life and Islamic branches of knowledge. Based on or specially favored with profound wisdom having its source in the Divine Wisdom or the Divine Name of the All-Wise, the Risale-i Nur Collection contains numerous principles, precepts, or maxims which are standards or brilliant criteria enabling people to think, believe, and live according to Islam, and to evaluate and judge things and events in Islam's light. They also provide people with the essentials or basic principles on which the branches of Islamic knowledge and Islamic science are based. Thus, we have tried to collect many of these principles in this book under certain titles, and in certain parts or sections according to the fields of thought and branches of knowledge to which they have a greater relevance.
