In accounts tracing the ancestry of Muhammad back to Ma'ad (and from there to Adam), Arab scholars alternate, with some citing the line as through Nebaioth, others Qedar.al-Mousawi in Boudreau et al., 1998, p. 219. Many Muslim scholars see Isaiah 42 (21:13-17) as predicting the coming of a servant of God who is associated with Qedar and interpret this as a reference to Muhammad.Zepp, Ira G.
