…it is an especial blessing that from among the descendants
of Abraham should have come all the Prophets of the children of Israel. This is
a blessing that God has granted to this descent: to Moses from His father and
mother, to Christ from His mother's line; also to Muhammad and the Báb, and to
all the Prophets and the Holy Manifestations of Israel. The Blessed Beauty is
also a lineal descendant of Abraham, for Abraham had other sons besides Ishmael
and Isaac who in those days migrated to the lands of Persia and Afghanistan,
and the Blessed Beauty is one of their descendants. (‘Abdu’l-Baha, table talks
