Asim bin Kulayb heard from his father that wealth came to Ali bin Abi Talib (may Allah be pleased with him) from Isfahan. He divided it into seven portions, and a piece of bread was left over; he broke it into seven pieces and placed a piece on each portion. Then he cast lots among the people as to who would take first.
