Wahshi ibn Harb
Waḥshī ibn Ḥarb al-Habashi, also known as Abu Dusmah, was a former slave of Jubayr ibn Mut'im before becoming a freedman and a Sahabi. He is best known for killing a leading Muslim fighter, Hamza ibn ‘Abd al-Muttalib, Muhammad's paternal uncle, prior to converting to Islam, and afterwards reportedly killing Musaylimah, the leader of an enemy apostate army waging war against the Muslims. Wahshi's grandson, Wahshi ibn Harb ibn Wahshi ibn Harb, was a Hadith narrator.
During the Battle of Uhud
Wahshi had been appointed by Hind bint Utbah to kill one of the three persons to avenge her father's death during the Battle of Badr.Wahshi said in reply, "I didn't approach Muhammad at all, because his companions are nearer to him than anyone else. Ali too is extraordinarily vigilant in the battlefield. However, Hamza is so furious that, while fighting, he does not pay any attention to any other side and it is possible that I may be able to make him fall by some trick or by taking him unawares." Hind was content with this and promised that if he was successful in performing the job she would set him free. Some believe that Jubayr made this promise to his slave as his uncle had been killed in the Battle of Badr.
