It is narrated from Hazrat Umrah bint Tabikh, she says: My mother sent me, so I bought a bam fish and put it in a basket. Its head came out from one side and its tail from the (other) side. Meanwhile, the Commander of the Faithful, Hazrat Ali (may Allah be pleased with him), passed by me and saw it. He said: This is a very pure thing; it satisfies the family.
