Tahmasp
Yes, though it originates from pre-Islamic Avestan Persian meaning 'strong horse,' it was borne by Shah Tahmasp I, a devout Muslim ruler of the Safavid Empire, making it historically Islamically valid.
The name is primarily associated with Shah Tahmasp I (1514-1576), the second Safavid Shah of Iran, who was a major patron of Persian miniature painting and Shi'a scholarship during the empire's golden age.
No, Tahmasp is not mentioned in the Quran. It is a Persian name of Zoroastrian/Avestan origin that predates Islam but was used by Muslim Persian royalty.
It remains extremely rare in modern usage, primarily found in historical contexts or among families seeking unique Persian heritage names distinct from common Arabic-derived options.
The name symbolizes physical strength, bravery, royal dignity, and the noble qualities of the horse, which in Persian culture represents loyalty, speed, and martial prowess.
