Quran 6:159 Al-An'am, ayah 159 of 165

إِنَّ ٱلَّذِينَ فَرَّقُوا۟ دِينَهُمْ وَكَانُوا۟ شِيَعًا لَّسْتَ مِنْهُمْ فِى شَىْءٍ ۚ إِنَّمَآ أَمْرُهُمْ إِلَى ٱللَّهِ ثُمَّ يُنَبِّئُهُم بِمَا كَانُوا۟ يَفْعَلُونَ ۝١٥٩

6:159 Lo! As for those who sunder their religion and become schismatics, no concern at all hast thou with them. Their case will go to Allah, Who then will tell them what they used to do.
