6:159
إِنَّ ٱلَّذِينَ فَرَّقُوا۟ دِينَهُمْ وَكَانُوا۟ شِيَعًا لَّسْتَ مِنْهُمْ فِى شَىْءٍ ۚ إِنَّمَآ أَمْرُهُمْ إِلَى ٱللَّهِ ثُمَّ يُنَبِّئُهُم بِمَا كَانُوا۟ يَفْعَلُونَ
inna alladhīna farraqū dīnahum wakānū shiyaʿan lasta min'hum fī shayin innamā amruhum ilā l-lahi thumma yunabbi-uhum bimā kānū yafʿalūna
As for those who have divided their religion and broken up into factions, have nothing to do with them [Prophet]. Their case rests with God: in time He will tell them about their deeds.
Verily, those who divide their religion and break up into sects (all kinds of religious sects), you (O Muhammad صلى الله عليه وسلم) have no concern in them in the least. Their affair is only with Allâh, Who then will tell them what they used to do.
