Sura 3 Ali 'Imran (Family of Imran), aya 105

1. وَلَا تَكُونُوا كَالَّذِينَ تَفَرَّقُوا وَاخْتَلَفُوا مِنْ بَعْدِ مَا جَاءَهُمُ الْبَيِّنَاتُ ۚ وَأُولَٰئِكَ لَهُمْ عَذَابٌ عَظِيمٌ

   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.

   3:105
