Tilka ommatun qad khalat laha ma kasabat walakum ma kasabtum wala tusaloona AAamma kano yaAAmaloona
That was a people that hath passed away. They shall reap the fruit of what they did, and ye of what ye do! Of their merits there is no question in your case!
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.
