Aal-'Imran - 3:67

مَا كَانَ إِبْرَاهِيمُ يَهُودِيًّا وَلاَ نَصْرَانِيًّا وَلَكِن كَانَ حَنِيفًا مُّسْلِمًا وَمَا كَانَ مِنَ الْمُشْرِكِينَ
[3:67]
Ibrahim was not a Jew nor a Christian but he was (an) upright (man), a Muslim, and he was not one of the polytheists.
Abraham was not a Jew nor yet a Christian; but he was true in Faith, and bowed his will to Allah's (Which is Islam), and he joined not gods with Allah.
Abraham was not a Jew, nor yet a Christian; but he was an upright man who had surrendered (to Allah), and he was not of the idolaters.
