Kitab al-Kharaj (The Book of Land-Tax) is an early Islamic treatise on public finance, taxation, and governance by the Hanafi jurist and chief judge Abu Yusuf (d. 182 AH / 798 CE) . Composed in response to a request from the Abbasid caliph Harun al-Rashid, the work serves as an authoritative guide on state revenues, the administration of conquered lands, and the fiscal duties of the sovereign .
Background and Purpose
The caliph Harun al-Rashid commissioned Abu Yusuf to draft a comprehensive reference manual to govern the assessment and collection of land taxes (kharaj), tithes (ushur), and obligatory alms (sadaqat) . Abu Yusuf aimed to establish an equitable, legally grounded fiscal system that protected cultivators and subjects from extortion and oppression by corrupt tax officials, while simultaneously securing state revenues and supporting the public interest .
Structure and Contents
The work is organized into fifteen main chapters, preceded by an epistle to Harun al-Rashid :
- Epistle to the Caliph: An introductory address counseling the caliph on the weight of authority and accountability before God, urging adherence to justice and the suppression of administrative abuses .
- Spoils of War (Ghana'im): Legal rulings on war booty based on the Quran, the Sunnah, and juristic consensus .
- Tribute and Land-Tax (Fay' and Kharaj): The classification and distribution of communal revenue .
- The Sawad of Iraq: Historical precedent and tax administration in southern Iraq .
- Syria and Upper Mesopotamia (al-Jazira): The conquests of these regions and their subsequent tax settlements .

- Concluding Matters: Treasury expenditures, including salaries for judges and provincial governors, as well as the rules of warfare against idolaters and the protocol for calling them to Islam .
Legal Method and Style
Abu Yusuf structures his arguments hierarchically: he begins each issue with evidence from the Quran and the Sunnah, followed by the administrative practices of the early Caliphs—chiefly Umar ibn al-Khattab . When textual sources or caliphal precedents do not yield a direct ruling, he consults the doctrines of Abu Hanifa and Ibn Abi Layla before exercising his own independent juristic reasoning (ijtihad bi-al-ra'y) .
Throughout the text, Abu Yusuf combines legal analysis with direct administrative instruction. He lays down strict qualifications for tax agents, advising the caliph to appoint individuals known for piety, trustworthiness, and moderation—instructing them to temper firmness with leniency, treat Muslims, non-Muslim subjects, the rich, and the poor with equal fairness, and avoid innovative abuses .
Reception and Publication
Kitab al-Kharaj is recognized as the earliest dedicated composition on Islamic public finance . Later scholars commended its frank counsel to the sovereign and its eloquence in organizing disparate aspects of fiscal administration .
During the Ottoman era, the book was translated into Ottoman Turkish three times . An early printed edition appeared at Bulaq in 1302 AH (1885 CE), featuring Muhammad ibn al-Hasan al-Shaybani's al-Jami' al-Saghir in its margins . A French translation by Edmond Fagnan was published in Paris in 1921 .
