The ruling on following the Sunnah while differing from the opinion of the people

Question:
Whenever the group comes to us, we go with them and follow the sound methodology. This is a matter that is not permissible. The one who acts asks: Is there anyone who has applied the words and deeds of the Messenger of Allah (peace and blessings be upon him) word for word in all his sayings and deeds in our time? If the people were to follow the Messenger’s entire practice, they would become strange and the people would find it objectionable, saying, “This is extreme.” Is this considered extremism and acting in a way that does not align with people’s opinions? Is it going against the will of the people?

Answer:
You do not look at the people, whether they praise you or blame you; you look at what you are upon: is it truth or falsehood? If what you are upon is truth, then adhere to it even if the people blame you; do not be deterred by those who belittle you or those who oppose you. But if what you are upon is falsehood, then you must turn away from it, even if the people praise you. If you are upon falsehood, leave it even if the people praise you. The criterion is what you are upon. If it is truth, then act for Allah and remain upon it, even if the people blame you and belittle you. The people belittled the Messenger (peace and blessings be upon him); they said he was a sorcerer, they said he was an outlier, they said he was insane, they said he was a teacher who teaches what others teach him and that he has no revelation from Allah (Glorified and Exalted is He). They said this about the Messenger (peace and blessings be upon him), so what about anyone other than the Messenger (peace and blessings be upon him)? So do not pay attention to the praise of the people or their blame, but look at what you are upon.
