The book 'Kitab al-Kasb wa Yalih Kitab Risalat al-Halal wal-Haram' (The Book of Earning, followed by the Epistle on the Lawful and the Unlawful) carries broad meanings that encompass all aspects of earning a livelihood. This comprehensive scope demonstrates the vast jurisprudential knowledge of Imam Muhammad ibn al-Hasan, the depth of his insight, and the precision of his expression. His work leaves no partial or complete form of livelihood unaddressed, including trade, industry, leasing, gifts, buying, selling, gathering wood, hunting, or what the earth produces and the sky grows. Praise be to this eloquent jurist and brilliant genius, who, with this single small term, covered every source of sustenance or benefit for mankind. In summary, Imam Muhammad ibn al-Hasan was the first to single out the topic of 'al-Kasb' (earning) for dedicated authorship, excelling in the research of its many important aspects. The book, along with its commentary by al-Sarakhsi, includes the verification and clarification of numerous matters with both scriptural and rational evidence.
