﴿ وَتَقَطَّعُوٓا۟ أَمْرَهُم بَيْنَهُمْ ۖ كُلٌّ إِلَيْنَا رَٰجِعُونَ ﴾

“But men have torn their unity wide asunder, [forgetting that] unto Us they all are bound to 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.
