The Slave Who Was Named the Prophet’s Son
Zayd ibn Haritha was captured in a tribal raid as a child and eventually purchased by Khadijah, who gave him to the Prophet as a gift. The Prophet freed him immediately and treated him as a son. His biological father and uncle came to ransom him; Zayd was given the choice — go with them or stay with the Prophet. He chose to stay.
The Prophet then publicly proclaimed him: “You are my son — you inherit from me and I from you.” The Arabs called him Zayd ibn Muhammad for years.
The Verse That Named Him
When Zayd divorced Zaynab bint Jahsh, the Prophet married her. This caused social controversy: in Arab custom, one did not marry the divorced wife of an adopted son — it was treated as equivalent to the wife of a biological son. A revelation came:
“And [remember, O Muhammad], when you said to the one on whom Allah bestowed favor and you bestowed favor: ‘Keep your wife and fear Allah,’ while you concealed within yourself that which Allah is to disclose. And you feared the people, while Allah has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you…” (33:37)
Two purposes: (1) the marriage was divinely ordained to prove that adopted sons are not the same as biological sons in Islamic law; (2) the Prophet’s initial reluctance was addressed directly by revelation — he had feared people’s reaction and kept this matter private. The Quran brought it into the open.
The Martyr of Mu’ta
Zayd ibn Haritha commanded the Muslim forces at the Battle of Mu’ta (629 CE) against the Byzantine-allied forces in southern Jordan. He was killed in the battle. The Prophet, receiving the news in Medina via revelation (it is said), announced the death before messengers arrived, and wept. “This is the eye grieving and the heart sorrowing, and we do not say except what is pleasing to our Lord.”
