Ash-Shura, 14 Ayah
42:14
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 مُرِيبٖ ١٤
Wa Mā Tafarraqū 'Illā Min Ba`di Mā Jā'ahumu Al-`Ilmu Baghyāan Baynahum ۚ Wa Lawlā Kalimatun Sabaqat Min Rabbika 'Ilá 'Ajalin Musammáan Laquđiya Baynahum ۚ Wa 'Inna Al-Ladhīna 'Ūrithū Al-Kitāba Min Ba`dihim Lafī Shakkin Minhu 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.
