We have dedicated a whole section to warn the sincere Muslims from the people of Bida'a that are known and have their methodology documented. The simple intention behind this aim is based on our love for our brothers and sisters for the sake of Allaah by calling towards the way of the salaf.
By allowing discussions on the people of bida'a, we are introducing argumentation, generating confusion which defeats the purpose of this forum and that is to call people to the way of Allaah.
Ibn Battah mentions an athaar from Sufyaan Ath-Thwaree (may Allaah have mercy on him) who is reported to have said:
"Whoever listens to a person of innovation leaves the protection of Allaah and is left to himself. "
And the same Tabi'ee that you have quoted (Al-Hasan) who said:
"Do not sit with the people of innovated beliefs, do not debate with them and do not listen to them."
Imaam al-Laalikaa'ee mentions all these athaars from the salaf towards the people of innovations in his Sharh Usool ul-I'tiqaad.
...
We do our utmost best to call people to the Sunnah while avoiding the discussions of baatil [falsehood].
...
may Allaah (Exalted is He) give us tawfeeq in purifying this forum and calling it to the authenthic and traditional Islaam, ameen.
