He chose to remain with Muhammad, who later adopted him as his son, making Zayd one of the first converts to Islam. Zayd played a significant role in early Islamic history, participating in key battles such as Badr and Uhud. His loyalty and bravery earned him the title of "the beloved" of the Prophet.
