Surah Al-An'am, Verse 159

إِنَّ ٱلَّذِينَ فَرَّقُواْ دِينَهُمۡ وَكَانُواْ شِيَعٗا لَّسۡتَ مِنۡهُمۡ فِي شَيۡءٍۚ إِنَّمَآ أَمۡرُهُمۡ إِلَى ٱللَّهِ ثُمَّ يُنَبِّئُهُم بِمَا كَانُواْ يَفۡعَلُونَ١٥٩

inna alladhīna farraqū dīnahum wakānū shiyaʿan lasta min'hum fī shayin innamā amruhum ilā l-lahi thumma yunabbi-uhum bimā kānū yafʿalūna

Indeed, those who have divided their religion and become sects - you, [O Muḥammad], are not [associated] with them in anything. Their affair is only [left] to Allāh; then He will inform them about what they used to do.
