Abdullah ibn Unais was a companion (Sahaba) of the Islamic prophet Muhammad.
The first was to kill Khaled bin Sufyan Al-Hathali who belonged to the Banu Lahyan tribe.
[1] Abdullah ibn Unais found Hudayr in the company of his wife, when asked about his identity.
Unais replied, "I am an Arab tribesman who has heard of you and the army you are raising to fight Muhammad, so I have come to join your ranks.
Some men requested that Muhammad send instructors to teach them Islam,[1] but the men were bribed by the two tribes of Khuzaymah who wanted revenge for the assassination of Khalid bin Sufyan by Muhammad's followers.
