Some argue for the permissibility of boycotting the people of innovation (bid'ah) by citing the story of the Prophet (peace and blessings be upon him) boycotting the three who were left behind. Is their argument correct?

Question:
He says: Honorable Shaykh, may Allah grant you success, regarding the boycott of the Prophet (peace and blessings be upon him) of the three who were left behind, some scholars cite this boycott as evidence that one should boycott the people of innovation. Is this correct?

Answer:
No, this is not correct. They were not people of innovation; they were Companions (may Allah be pleased with them). What happened to them was that they were left behind. There is no doubt that being left behind by the Prophet (peace and blessings be upon him) is not a trivial matter, but they repented, and Allah accepted their repentance. This does not diminish their status as Companions or their rights (may Allah be pleased with them). Allah sent down their repentance. And , and Allah mentioned what happened to them of regret and that , Allah mentioned their regret and what they experienced of distress, then He turned to them in mercy.
As for the people of innovation, they are a different category. Innovations are introducing into the religion what is not part of it; that is what innovations are. These people did not introduce into the religion what is not part of it; rather, they were only left behind from the expedition, and they had no excuse. They were left behind and had no excuse. Yes.
