Ayman ibn Ubayd

Ayman ibn ʿUbayd (Arabic: أَيْمَن ابْنِ عُبَیْد), was an early Muslim and companion of the Islamic prophet Muhammad.

He was the son of Barakah, who helped raise Muhammad, by her first husband Ubayd ibn Zayd of the Banu Khazraj tribe. Through his mother's second marriage to Zayd ibn Harithah, he was the half-brother of Usama ibn Zayd.

Ayman was killed fighting for the Muslim forces against enemy Arab tribes in the Battle of Hunayn.

Ayman's son, al-Hajjaj ibn Ayman was born during the lifetime of Muhammad and ahadith (traditions) of Muhammad have been quoted from al-Hajjaj in Islamic literature, including in the Sahih al-Bukhari.
