Commercial Law and Family Law in the Riwayah

The commercial law and family law sections of the Riwayat ash-Shaybani document some of the most practically significant Hanafi-Maliki differences in the formative period of Islamic jurisprudence. Ash-Shaybani's running commentary provides the Hanafi positions on dozens of specific legal questions where the schools diverged.

In commercial law, the differences between the schools on the validity of certain contracts receive direct treatment. The Maliki school developed from the living practice of Madinah, in which many commercial arrangements had evolved organically and were accepted as established practice (amal ahl al-Madinah). The Hanafi school, based in the more commercially sophisticated environment of Iraq, had developed a systematic approach to commercial contracts that sometimes arrived at different conclusions.

The famous Hanafi permission for the murabahah contract (cost-plus sale with disclosed profit) is discussed in light of Malik's positions on commercial dealings. The Hanafi-Maliki difference on certain types of agricultural contracts (muzarabah and musaqah) is also captured, reflecting the different economic contexts in which each school developed its commercial jurisprudence.

For family law, the question of the guardian's role in marriage receives attention. Malik held that a marriage without a guardian's consent is invalid — a position shared with the Shafi'i and Hanbali schools. Ash-Shaybani presents the Hanafi position: a sane adult woman may contract her own marriage without a guardian, though it is preferable to have one. His presentation of the Hanafi position with its reasoning in dialogue with Malik's practice provides the earliest systematic comparative treatment of this important legal question.

The divorce sections of the Muwatta, and ash-Shaybani's commentary on them, address the types and conditions of valid divorce, the waiting period (iddah), and the maintenance obligations after divorce. The Hanafi and Maliki schools shared many positions in this area while differing on specific details, and ash-Shaybani's commentary identifies both the agreements and the differences with precision.
