Zaynab is an Arabic name borne by a daughter and a granddaughter of the Prophet Muhammad, which makes it one of the most beloved girls' names in the Muslim world. Its meaning is debated; it is usually explained as the name of a "fragrant flowering tree" or as "beauty". The spelling Zainab is more common in the United States, but Zaynab has climbed too, from number 1621 in 2015 to number 1492 in 2025, its best rank yet.
