Both Christians and Arabs were genealogically tied to Hagar in the patristic tradition

Evidence

A long tradition that goes back to Eusebius sees in the Arabs the descendants of Hagar, Abraham’s slave-wife, hence the name “Agarenes.” Beginning with Paul’s figurative reading, however, the Jews were said to be Hagar’s descendants, as well. Richard Southern documents some of this conflicted tradition in his “Western Views of/slam, 16-q, 16 n. — Gil Anidjar, The Jew, the Arab, 923
