Quran 6:159 from Surah Al-An'aam on Divine Marvels.
إِنَّ ٱلَّذِينَ فَرَّقُواْ دِينَهُمۡ وَكَانُواْ شِيَعٗا لَّسۡتَ مِنۡهُمۡ فِي شَيۡءٍۚ إِنَّمَآ أَمۡرُهُمۡ إِلَى ٱللَّهِ ثُمَّ يُنَبِّئُهُم بِمَا كَانُواْ يَفۡعَلُونَ
English translation: Indeed those who divide their religion and become sects you are not with them in anything Only their affair (is) with Allah then He will inform them of what they used to do
Transliteration: inna alladhina farraqu dinahum wakanu shiya'an lasta min'hum fi shayin innama amruhum ila al-lahi thumma yunabbi-uhum bima kanu yaf 'aluna
