Surah Al-Bayyinah — Ayah 2

لَمْ يَكُنِ ٱلَّذِينَ كَفَرُوا۟ مِنْ أَهْلِ ٱلْكِتَـٰبِ وَٱلْمُشْرِكِينَ مُنفَكِّينَ حَتَّىٰ تَأْتِيَهُمُ ٱلْبَيِّنَةُ

Those who disbelieved among the People of the Scripture and the polytheists were not to be parted [from misbelief] until there came to them clear evidence -

فِيهَا كُتُبٌ قَيِّمَةٌ

Within which are correct writings.

وَمَا تَفَرَّقَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ إِلَّا مِنۢ بَعْدِ مَا جَآءَتْهُمُ ٱلْبَيِّنَةُ

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