Commentary
And when they thought that they were on the right path, He set for them a proof of its invalidity that is clearer than anything, and no one can stop in it. That is because it is not possible for something to be characterized by negating something and affirming it at the same time. So He said, replacing: "from those who divided" when they separated from "their religion" which is the original nature. Each group among them worshiped something and followed a religion other than the religion of others. This is the meaning of "and they were" meaning by their effort and diligence in that separating division "parties" (p-91) meaning factions allied together, each one of them supporting whoever adheres to its religion against those who oppose them, until some of them declared others to be disbelievers and permitted bloodshed and property. It was certainly known that they are all not upon the truth.
And when this matter is something to be wondered at its occurrence, He increased the wonder by saying in continuation: "Every party" meaning among them "is pleased with what they have" meaning specifically of the delusion they have adopted. "Rejoicing" thinking that they have encountered the truth and succeeded in it without others.
