مَا كَانَ اِبْرٰهِیْمُ یَهُوْدِیًّا وَّلَا نَصْرَانِیًّا وَّلٰكِنْ كَانَ حَنِیْفًا مُّسْلِمًا وَمَا كَانَ مِنَ الْمُشْرِكِیْنَ ۟

Maa kaana Ibraaheemu Yahoodiyyanw wa laa Nasraa niyyanw wa laakin kaana Haneefam Muslimanw wa maa kaana minal mushrikeen

“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.”
