Shaybah ibn Rabīʿah (Arabic: شيبة بن ربيعة) (c. 560–624) was the brother of Utbah ibn Rabi'ah belonging to the clan of Banu Abd Shams (parent clan of Banu Umayyah) from the tribe of Quraysh of Mecca. He was also a champion of the Meccan army sent along with his brother Utbah and his nephew Walid ibn Utbah in the Battle of Badr^[1] in around 624 CE (2 AH). In a three against three match before the actual battle began, he was killed by Ubaydah ibn al-Harith. Shayba married twice. First, he married with Fa'ra bint Harb ibn Umayya, Abū Ṣufyān ibn Ḥarb's sister. By her, he had children named Asim, Zaynab, and Ubayd-Allah. Second, he married with Umm Sharak (Safiyya) bint Waqdan from Banu Amir ibn Luayy. By her, he had children named Ramla, Fatima, and Aisha, who all would eventually become Muslim. Shayba remained pagan until his death at Badr.

   Utbah   Shaybah

A tradition from Sunan Abi Daud that relates the incident at the Battle of Badr:

Narrated from Ali: Utbah ibn Rabi'ah came forward followed by his son and his brother and cried out: Who will be engaged in single combat? Some young men of the Ansar responded to his call. He asked: Who are you? They told him. He said: We do not want you; we, in fact, want only our cousins. Muhammad said, "Get up Hamzah. Get up Ali. Get up Ubaydah ibn al-Harith. Hamzah went forward to Utbah, I went forward to Shaybah; and after two blows had been exchanged between Ubaydah and al-Walid, they wounded one another severely; so we turned against al-Walid and killed him, and we carried Ubaydah away.
