Banu Sulaym
The tribe does not appear to have played any significant role in the early Muslim conquests, and for the most part remained in the Nejd. Only in the early 8th century did some of the Hilal (and the Banu Sulaym) move to Egypt. Many followed, so that the two groups became numerous in Egypt. During the Abbasid Caliphate, the Hilal were known for their unruliness.
