Verse 14

وَمَا تَفَرَّقُوٓا۟ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ إِلَىٰٓ أَجَلٍ مُّسَمًّى لَّقُضِىَ بَيْنَهُمْ وَإِنَّ ٱلَّذِينَ أُورِثُوا۟ ٱلْكِتَـٰبَ مِنۢ بَعْدِهِمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ

And they were not divided except after they received the knowledge, because of jealousy amongst them. If it were not for a word, preordained by your Lord, they would have been judged immediately. And indeed those who inherited the scripture afterward are full of doubt.
