Zayd is an Arabic name that means "growth" or "abundance", from the verb zada, to increase. Zayd ibn Harithah, the adopted son of the Prophet Muhammad and one of the first Muslims, made it a classic name throughout the Islamic world. In the United States Zayd was still number 1074 in 2015, entered the top 1000 in 2017 and has climbed every year since to 633 in 2025, its highest rank so far.
