The domain of "furūʿ al-fiqh" (lit. branches of fiqh) is traditionally divided into "ʿibādāt" (rituals or acts of worship) and "muʿāmalāt" (social relations). Many jurists further divided the body of substantive jurisprudence into "the four quarters", called rituals, sales, marriage and injuries. Each of these terms figuratively stood for a variety of subjects. For example, the quarter of sales would encompass partnerships, guaranty, gifts, and bequests, among other topics. Juristic works were arranged as a sequence of such smaller topics, each called a "book" ("kitab"). The special significance of ritual was marked by always placing its discussion at the start of the work.
