An example of the Báb’s undeviating fairness in business transactions

His [the Báb’s] scrupulous attention to detail and His undeviating fairness in transactions became widely known in the region. A man who had consigned to Him some goods to sell was astonished to find, when he received his money, that it was more than could be obtained at current prices. He wanted to return some of it. The Báb told him that it was only fair and just that he should be given that particular sum, because his goods would have fetched exactly that amount had they been offered for sale when the market was at its best.

At the age fifteen the Báb joined His uncle-guardian in business and afterwards moved to Búshihr

According to Hájí Mirza Habíbu’lláh’s narrative, He [the Báb] joined Hájí Mirza Siyyid ‘Ali, His uncle-guardian, in business when He was fifteen years old, [Islamic law specifies fifteen as the age of maturity] and shortly afterwards moved to Búshihr. Pages of commercial accounts which He kept put it beyond doubt that the Báb left Shiraz for Búshihr when He was nearly sixteen. There can be little doubt that at an early age the Báb took over the complete management of the trading-house in Búshihr.
