The east African societies relied on Islam to help create their world since their identity derived not only from commercial links with co-religionists but on specific modes of social and commercial behavior. The Muslim religion gave prescriptions as to everyday conduct. The Koran had specific admonitions on fair practice in the market place. The Koranic injunction to have balance scales led to the appearance of a market inspector called the muhtash whose specific job was to oversee local transactions and check weights and measures among other duties.\"  <a class=\"fw-bold\" href=\"https://www.zotero.org/groups/1051264/seshat_databank/items/3WJ42ET7\">[Rothman 2002, p. 80]</a>  \"The \" metical \" was the gold standard on the Azanian coast at the time of the arrival of the Portuguese. It was not a coin, but a specific quantity of gold dust. Like all weights and measures its value varied from time to time and in different places, but it may be taken to have been worth about eleven shilling* and sixpence. This value is the average of a series of transactions referred to by Portuguese writers of the sixteenth and seventeenth centuries.\"  <a class=\"fw-bold\" href=\"https://www.zotero.org/groups/1051264/seshat_databank/items/CG9EGFB2\">[Pearce 1920, p. 62]</a>",
