Waqaloo koonoo hoodan aw nasara tahtadoo qul bal millata ibraheema haneefan wama kana mina almushrikeena
They say: "Become Jews or Christians if ye would be guided (To salvation)." Say thou: "Nay! (I would rather) the Religion of Abraham the True, and he joined not gods with Allah."
Say ye: "We believe in Allah, and the revelation given to us, and to Abraham, Isma´il, Isaac, Jacob, and the Tribes, and that given to Moses and Jesus, and that given to (all) prophets from their Lord: We make no difference between one and another of them: And we bow to Allah (in Islam)."
So if they believe as ye believe, they are indeed on the right path; but if they turn back, it is they who are in schism; but Allah will suffice thee as against them, and He is the All-Hearing, the All-Knowing.
