quran:21:93 –

And ˹yet˺ they divided their affair among themselves, ˹but˺ all to Us will return.  

But they, that is to say, some of those being addressed, fragmented their affair among themselves, that is, they became divided in the matter of their religion, and at variance over it — these are the ˹different˺ sects of the Jews and the Christians. God, exalted be He, says: All shall return to Us, and We will requite each according to his deeds.
القرآن:٢١:٩٣ –

وَتَقَطَّعُوا أَمْرَهُمْ بَيْنَهُمْ ۖ كُلٌّ إِلَيْنَا رَاجِعُونَ  

{وتَقطَّعوا} أي بعض المخاطبين {أمرهم بينهم} أي تفرقوا أمر دينهم متخالفين فيه، وهم طوائف اليهود والنصارى قال تعالى: {كل إلينا راجعون} أي فنجازيه بعمله.
