Uqba ibn Nafi
The above account is disputed by some historians, who prefer the earlier 9th-century sources. According to these, Abu al-Muhajir had no connection with Kusaila, nor did Uqba ibn Nafi until he was ambushed at Tahudha. These earlier sources also describe Kusaila as a Christian, not a Muslim convert. They do agree, however, that he led a Berber force when he defeated Uqba.
