I have read it, but it is not short, and so I can't possibly remember all the details. That said I do not remember much/any mention of Islamic jurisprudence: it was more a renaissance of Roman law (see Code of Justinian and
Corpus Juris Civilis) The first 1-2 chapters actually go into Roman law (and before), as that was used as the initial base. There's a thread of ancient law even in the present day:

From the little I know about Islamic jurisprudence, specifically through the works of Toby Huff,[1] the tribunals were more 'private' and the rulings were done more by something that we'd call arbitration, and 'case files' would remain in the judge's/arbitrator's possession.
