In the great messianic prophecy of
Daniel 7, the Son of Man is called the "ancient of days" (v. 22), a
phrase used twice in the same passage of God the Father (vv. 9, 13). (Norman L. Geisler and Abdul Saleeb, Answering
Islam: The Crescent in Light of the Cross [rev ed.; Grand Rapids, Mich.:
Baker Books, 2002], 251)
