3:105
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
Do not be like those who, after they have been given clear revelation, split into factions and fall into disputes: a terrible punishment awaits such people.
And be not as those who divided and differed among themselves after the clear proofs had come to them. It is they for whom there is an awful torment.
