Rabëÿah ibn al-ḤÃÂrith () (c.566-c.640) was a first cousin and companion of the Islamic prophet Muhammad.
Rabiÿa ibn al-Harith ibn ÿAbd al-Muttalib was a cousin of the Prophet Muhammad, and was about two years older than his uncle Abbas ibn Abd al-Muttalib. Before Islam he worked as a merchant, sometimes in partnership with Uthman ibn Affan.
He did not take part in the Battle of Badr with Quraysh because he was away on a trading journey in Syria. Rabiÿa embraced Islam around the time of the Battle of the Trench, migrating to Medina together with his uncle al-ÿAbbas and his brother Nawfal ibn al-Harith. At Khaybar, Muhammad allotted him 100 wasqs of produce annually and praised him, saying:
Rabiÿa was present at the Conquest of Mecca, and fought alongside Muhammad at Hunayn and Taþif, where he was among those who stood firm. He later lived in Medina and died there in 23 AH (644 CE) during the caliphate of Umar ibn al-Khattab. Some reports place his death earlier, in 13 AH.
Rabiÿa had several children, including: Muhammad, ÿAbd Allah, al-Harith, al-ÿAbbas, Umayya, ÿAbd Shams, Abd al-Muttalib ibn Rabiÿa ibn al-Harith, Arwa al-Kubra, and Hind, whose mother was Umm al-Hakam bint al-Zubayr ibn ÿAbd al-Muttalib; and Arwa al-Sughra, whose mother was a concubine.
He was a son of Al-Harith ibn Abd al-Muttalib of the Hashim clan of the Quraysh in Mecca.
He married his cousin Umm al-Hakam bint al-Zubayr and they had nine children.
It is said that Rabi'ah did not fight at the Battle of Badr in 624 because he was in Syria at the time.
In 627, at the time of the Battle of the Trench, he converted to Islam and emigrated to Medina.
Rabi'ah's son Adam was a small child living with a foster-mother from the Bakr tribe. The Bakr were at war with the Hudhayl. Adam crept out in front of the tents and was caught in the cross-fire of the battle. A rock thrown by a Hudhayl man hit and crushed his head, which killed him.
Rabi'ah intended to demand blood-money or a counter-killing from the Hudhayl for the death of his son. Before this could happen, Muhammad conquered Mecca. On that day Muhammad cancelled all bloodwit debts and he specifically named Rabi'ah's case as the first to be cancelled. However, Ibn Ishaq asserts that the cancellation was declared two years later, at the Farewell Pilgrimage of 632.
<blockquote>All blood shed in the pagan period is to be left unavenged. The first claim on blood I abolish is that of Ibn Rabi'ah ibn al-Harith ibn Abd al-Muttalib. It is the first blood shed in the pagan period which I deal with.</blockquote>
Hence Muhammad prevented Rabi'ah from claiming revenge from the killer.
Rabë'ah and his brother Abà « SufyÃÂn were among the ten people who did not flee in the Battle of Hunayn.
He is involved in the Hadith of the ten promised paradise.
Rabi'ah died after 636 but before 644.
