Surat Al-An'aam (The Cattle) - الأنعام

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

Surely they who divided their religion into parts and became sects, you have no concern with them; their affair is only with Allah, then He will inform them of what they did.
