A rich man, possessing 1000 dinars, took an oath to leave 100 dinars to each one of his ten sons. He lost fifty dinars. Before dying, he gave 900 to the nine sons. The youngest asked him what he would leave him and the father replied, “I must keep my oath. To you I leave 20 dinars out of the fifty, for 30 are required for burial/' I leave you ten friends worth more than 1000 dinars.” The nine took their money, went away and the youngest invited the ten friends, who were pleased with his attention, thus continuing the friendship of the father. Each one gave him a cow and money and he soon became much richer than his father had been, proving the truth of his father's statement.
