About the origin of the name "Zarrinnaal" various stories are told: One says the family's ancestor rode in a battle against a foreign power a horse with golden horseshoes (Persian Zarrin Naal) and therefore was named after [REF].
In fact the term naal or to be more precise na'al (نعل) means in modern Persian of today "horseshoe", but also is Nominative Singular of the Arab word na'eleyn meaning "shoes, slippers",[REF] and was the common term for slippers.
