Ash-Shuraa 42:14

Wama tafarraqoo illa minbaAAdi ma jaahumu alAAilmu baghyan baynahum walawlakalimatun sabaqat min rabbika ila ajalin musamman laqudiyabaynahum wa-inna allatheena oorithoo alkitaba minbaAAdihim lafee shakkin minhu mureeb

And they did not become divided until after knowledge had come to them - out of jealous animosity between themselves. And if not for a word that preceded from your Lord [postponing the penalty] until a specified time, it would have been concluded between them. And indeed, those who were granted inheritance of the Scripture after them are, concerning it, in disquieting doubt.

And they were not divided, in jealousy with each other, but after the knowledge had come to them. Had it not been for a word that had come forth earlier from your Lord (and was effective) until a specified time, the matter would have been decided between them. And those who were made to inherit the Book after them are in confounding doubt about it.
