There was no disagreement in creed during the blessed centuries, and those who opposed them are not a standard

Question:
He says: Honorable Shaykh, may Allah grant you success, it is said that disagreement in creed did not occur until after the blessed centuries, and the Khawarij emerged during the time of the Companions and in the first century.

Answer:
There was no disagreement among the people of the Sunnah and the community regarding the foundations of creed. As for the fact that there are those who oppose them, we are not speaking about the opponents; we are speaking about the people of the Sunnah and the community. We say that there was no disagreement among them. There was no disagreement among the Companions, the Tabi'un, and the generation following the Tabi'un. As for those other than the people of the Sunnah and the community, they are not a standard. Yes. Indeed, the disbelievers existed during the time of the Messenger of Allah (peace and blessings be upon him); they opposed the message and denied the message of the Messenger. We say that it is not valid because there is disagreement in it. Not every disagreement is considered. The poet said: "Not every disagreement that comes is considered, except a disagreement that has a share of reflection." Yes.
