For a long time, German-speaking Muslims and those interested in Islam have desired a comprehensive guide and reference work in German that covers all schools of Islamic jurisprudence, reflecting the diversity of Islamic legal thought and addressing the circumstances in Germany.

This treatise meets that need with the necessary thoroughness across 832 pages. It belongs to the literary genre known as Ilm al-Hâl works, which present the opinions and legal rulings of one, several, or all schools of law, without, except for a few exceptions, listing the sources of legal decisions (Hadiths, Quranic verses) or legal principles in detail.

Thus, the work is understood as a presentation of classical Islamic legal and ethical teachings, with only occasional inclusion of contemporary legal opinions (Fatâwâ). Furthermore, topics not strictly part of Ilm al-Hâl are also addressed. For example, the legal sciences and schools of law are introduced, and the significance and role of custom in Islamic societies and law are acknowledged.
