Ali 'Imran 3:67

Ma kana ibraheemuyahoodiyyan wala nasraniyyan walakinkana haneefan musliman wama kana minaalmushrikeen

Abraham was neither a Jew nor a Christian, but he was one inclining toward truth, a Muslim [submitting to Allāh]. And he was not of the polytheists.

Ibrāhīm was neither a Jew nor a Christian. But he was upright, a Muslim, and was not one of those who associate partners with Allah.
