Al-Adab al-Mufrad

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that it used to be said: "Where is the gambling camel?" Then ten men would gather and, in exchange for the ten calves of a camel, would buy one camel. And it was such that as the she-camels gave birth to calves, each person would give one. Then they would cast arrows, and it would be divided into nine shares. Then, through the arrows, each time one share would be reduced until it became the share of one man (whose arrow was drawn), and all the rest would pay one camel calf each as compensation (and give it to the person from whom the camel was bought). Thus, this was the gambling that was prevalent among the Arabs.
