The Ruling on Associating with Those Who Deviate and Explaining the Method of Warning Against Them

Question:
...from the people of the Sunnah and the community, and then we detail the ruling on those who deviate, whether it is declaring them misguided, declaring them disbelievers, or something more or less than that. This requires study. All right, Shaykh, in the case of... hmm? Do they associate with them, for example, or boycott them?

Answer:
Associating with them, if the intention is to call them to adhering to the Sunnah and abandoning error, is good. This is part of calling people to Allah. However, if it is for the sake of their company and companionship without calling them and without clarifying the truth, it is not permissible. It is not permissible for a person to associate with those who deviate except in a manner that has a legal benefit: calling them to Islam and clarifying the truth to them, so that perhaps they may return.
Yes, we warn against those who deviate in general, and we say: We must adhere to the path of the people of the Sunnah and the community, and abandon those who deviate from the people of the Sunnah and the community, whether their deviation is major or minor. Because if we are lenient regarding deviation, matters may develop and become exaggerated. Deviation is never permissible. Adhering to the path of the people of the Sunnah and the community in both major and minor matters is obligatory.
