How come you "think" that prophet Ibrahim (you call Abraham?) is Jewish??? Are you aware that Judaism came hundreds of years AFTER prophet Ibrahim already died?? Your ancestors made-up this religion called "Judaism" many years after Musa (Moses) died, which is even far away from Abraham.

In fact prophet Abraham was a Muslim - a submitter to one God, and believers in all messengers. Musa (Moses) was Muslim too, all prophets who came after Abraham, and all those who followerd them were called Muslims.

Believer in all human messengers that God sent to people. >> this is the definition of Muslim.
