﴿ وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَٰتُ ۚ وَأُو۟لَٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌۭ ﴾

“And be not like those who have drawn apart from one another and have taken to conflicting views after all evidence of the truth has come unto them: for these it is for whom tremendous suffering is in store”
