Surah Al-Bayyinah, Verse 4

وَمَا تَفَرَّقَ ٱلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ إِلَّا مِنۢ بَعۡدِ مَا جَآءَتۡهُمُ ٱلۡبَيِّنَةُ٤

wamā tafarraqa alladhīna ūtū l-kitāba illā min baʿdi mā jāathumu l-bayinatu

Nor did those who were given the Scripture become divided until after there had come to them clear evidence.
