Ancestry in Faith:It is the originality of Faith.
Proof from HOLY QUR'AN:
AL BAQARA_2:133_
"Nay, but you [yourselves, O children of Israel,] bear witness that when death was approaching Jacob, he said unto his sons: "Whom will you worship after I am gone?"
They answered: "We will worship thy God, the God of thy forefathers Abraham and Ishmael
and Isaac, the One God; and unto Him will we surrender ourselves."

107 I.e., "in the religious traditions to which you adhere". It is to be noted that the
conjunction am which stands at the beginning of this sentence is not always used in the
interrogative sense ("is it that ...?"): sometimes - and especially when it is
syntactically unconnected with the preceding sentence, as in this case - it is an
equivalent of bal ("rather", or "nay, but"), and has no interrogative connotation.

108 In classical Arabic, as in ancient Hebrew usage, the term ab ("father") was applied
not only to the direct male parent but also to grandfathers and even more distant
ancestors, as well as to paternal uncles: which explains why Ishmael, who was Jacob's
uncle, is mentioned in this context. Since he was the first-born of Abraham's sons,
his name precedes that of Isaac.
