The general public refers to Abrahamic religions and means Judaism, Christianity, and Islam, and apparently sometimes even Baha'i. This is nonsense on stilts. Islam cannot trace its origins to Abraham and neither can the smaller Baha'i. Abraham knew nothing about these two man-made religions and monotheism is not a common denominator in any example. Any attempt to construct genealogies showing Muhammad to be a descendant of Ishmael except in a general sense fails for lack of evidence. Ishmael did not accept Judaism, was expelled from Israel, and therefore is not an heir of Abraham. Baha'i, a little over a century old, is like Islam in a lack of a connection. Personally, I think the idea that Islam is an Abrahamic religion should be dismissed as a misleading term. As Milton noted, Allah is just another name for Satan.
