وَءَاتَيْنَٰهُم بَيِّنَٰتٍۢ مِّنَ ٱلْأَمْرِ ۖ فَمَا ٱخْتَلَفُوٓا۟ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ ۚ إِنَّ رَبَّكَ يَقْضِى بَيْنَهُمْ يَوْمَ ٱلْقِيَٰمَةِ فِيمَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ
And gave them plain commandments. And they differed not until after the knowledge came unto them, through rivalry among themselves. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.
