When we had finished the meal, he ate the sweetmeats, then drank fuqqāʿ [barley-beer] after that; we took betel and withdrew. It was only a short while before the treasurer came to me and said, "Send your companions to collect the money." I sent them and returned to my house after sunset, and found the money there: three bags containing six thousand two hundred and thirty-three tankas. That was the exchange value of the fifty-five thousand that were my debt, and of the twelve thousand that he had previously ordered for me, after deduction of the tenth according to their custom. The tanka is worth two and a half dinars of Maghribi gold.
