Adi bn Hatim is a leader of the Arab tribe of Tayy, and one of the companions of Muhammad.

He is the son of the poet Hatim al-Tai who was widely known for his chivalry and generosity among Arabs.

Adi remains antagonistic to Islam for about twenty years until he converts to Islam from Christianity in 630 (9th year of Hijra).

Adi inherits the domain of his father and is confirmed in the position by the Tayy people.

A great part of his strength lies in the fact that a quarter of any amount they gain as booty from raiding expeditions has to be given to him.
