Al 'Imran, 67 Ayah
3:67
مَا كَانَ إِبۡرَٰهِيمُ يَهُودِيّٗا وَلَا نَصۡرَانِيّٗا وَلَٰكِن كَانَ حَنِيفٗا مُّسۡلِمٗا وَمَا كَانَ مِنَ ٱلۡمُشۡرِكِينَ ٦٧
Mā Kāna 'Ibrāhīmu Yahūdīyāan Wa Lā Naşrānīyāan Wa Lakin Kāna Ĥanīfāan Muslimāan Wa Mā Kāna Mina Al-Mushrikīna
Abraham was neither a Jew nor a Christian, but he was one inclining toward truth, a Muslim [submitting to Allah ]. And he was not of the polytheists.
