Ali 'Imran 105

وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَـٰتُ ۚ وَأُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌ

walā takūnū ka-alladhīna tafarraqū wa-ikh'talafū min baʿdi mā jāahumu l-bayinātu wa-ulāika lahum ʿadhābun ʿaẓīmun

And do not be like the ones who became divided and differed after the clear proofs had come to them. And those will have a great punishment
