Risāla fī al-ʿAdad

Risāla fī al-ʿAdad is a mathematical treatise written by Al-Muhaqqiq al-Hilli, a 13th-century Islamic scholar and jurist. The text focuses on number theory and arithmetic calculations within Islamic law and religious practices. The work contains explanations of mathematical principles as they apply to Islamic inheritance law, commercial transactions, and ritual obligations. Al-Hilli presents methods for calculating shares of inheritance, proportions for Zakat (religious tax), and other quantitative aspects of Islamic law. The treatise reflects the integration of mathematical reasoning with religious jurisprudence in medieval Islamic scholarship. It serves as an example of how Islamic scholars applied rigorous mathematical principles to solve practical religious and legal questions. Through its systematic approach to numbers in Islamic law, the work illuminates the relationship between exact sciences and religious thought in classical Islamic civilization.

There are not enough internet reviews to create a summary of this book. Instead, here is a summary of reviews of Al-Muhaqqiq al-Hilli's overall work: Readers commend Al-Muhaqqiq al-Hilli's "Shara'i al-Islam" for its systematic organization and clear presentation of complex Shia legal concepts. Students and scholars note the text's accessibility despite its age, with one seminary student on an Islamic studies forum writing that it "breaks down difficult principles into digestible sections." Readers appreciate: - Logical structuring of legal arguments - Clear explanations of reasoning behind rulings - Comprehensive coverage of Shia jurisprudence - Continued relevance to modern legal questions Common criticisms: - Dense technical language requires background knowledge - Limited English translations available - Some sections need updated commentary for contemporary context Due to the specialized nature of his works, most reviews come from academic sources and Islamic seminary discussions rather than consumer review sites. No Goodreads or Amazon ratings are available for English translations. Persian and Arabic language forums feature scholarly discussions but few formal reviews.
