Aal-'Imran - 3:105

وَلاَ تَكُونُواْ كَالَّذِينَ تَفَرَّقُواْ وَاخْتَلَفُواْ مِن بَعْدِ مَا جَاءهُمُ الْبَيِّنَاتُ وَأُوْلَـئِكَ لَهُمْ عَذَابٌ عَظِيمٌ
[3:105]
And be not like those who became divided and disagreed after clear arguments had come to them, and these it is that shall have a grievous chastisement.
Be not like those who are divided amongst themselves and fall into disputations after receiving Clear Signs: For them is a dreadful penalty,-
And be ye not as those who separated and disputed after the clear proofs had come unto them. For such there is an awful doom,
