The opening as it read in 2025

Zayd ibn Ḥāritha al-Kalbī ( Arabic : زيد بن حارثة الكلبي ) ( c. 581–629 CE ), was an early Muslim , Sahabi and the adopted son of the Islamic prophet, Muhammad . He is commonly regarded as the fourth person to have accepted Islam , after Muhammad's wife Khadija , Muhammad's cousin Ali , and Muhammad's close companion Abu Bakr . Zayd was a slave that Hakim ibn Hizam , Khadija's nephew, bought for her at a market in Ukaz . Zayd then became her and Muhammad’s adopted son. This father-son status was later annulled after Muhammad married Zayd’s ex-wife, Zaynab bint Jahsh . Zayd was a commander in the early Muslim army and led several early military expeditions during the lifetime of Muhammad. Zayd led his final expedition in September 629 CE, and set out to raid the Byzantine city of Bosra . However the Muslim army was intercepted by Byzantine forces and Zayd was subsequently killed at the Battle of Mu'tah .
