﴿ وَتَقَطَّعُوٓا۟ أَمْرَهُم بَيْنَهُمْ ۖ كُلٌّ إِلَيْنَا رَٰجِعُونَ ﴾

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

(And they have broken their religion (into fragments) among them) they disagreed among themselves concerning their religion, i.e. the Jews, Christians and Magians, ((yet) all) all the different groups (are returning unto Us).
