Ibn `Umar reported God's messenger as saying, "May God grant forgiveness ( ghafara ) to Ghifar and grant peace ( salama ) to Aslam; but `Usayya has disobeyed ( asa ) God and His messenger[*]." *As can be seen from the Arabic words given in brackets, these phrases all make use of roots connected with the names of the tribes in question. (Bukhari and Muslim.)
