Surah Ash-Shuraa, Verse 14

وَمَا تَفَرَّقُوٓاْ إِلَّا مِنۢ بَعۡدِ مَا جَآءَهُمُ ٱلۡعِلۡمُ بَغۡيَۢا بَيۡنَهُمۡۚ وَلَوۡلَا كَلِمَةٞ سَبَقَتۡ مِن رَّبِّكَ إِلَىٰٓ أَجَلٖ مُّسَمّٗى لَّقُضِيَ بَيۡنَهُمۡۚ وَإِنَّ ٱلَّذِينَ أُورِثُواْ ٱلۡكِتَٰبَ مِنۢ بَعۡدِهِمۡ لَفِي شَكّٖ مِّنۡهُ مُرِيبٖ١٤

wamā tafarraqū illā min baʿdi mā jāahumu l-ʿil'mu baghyan baynahum walawlā kalimatun sabaqat min rabbika ilā ajalin musamman laquḍiya baynahum wa-inna alladhīna ūrithū l-kitāba min baʿdihim lafī shakkin min'hu murībin

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.
