Qur'an 3:105 · Aal-i-Imraan

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

(105) 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
