Sufis claim that there is a thing in Islam called bidah hasanah ‘good bidah’ however this is wrong and incorrect. The scholars of Ahlus Sunnah Wal Jamaah do not believe in bidah hasanah they believe all bidah is haram. Only Sufi scholars believe in the permissibility of bidah hasanah.
Ahlu Ahwaa (the people of desirers) is another name for Ahlu Bidah (the people of innovation).
Statements On Ahlu Bidah By The Scholars Of Ahlus Sunnah Wal Jamaah
Sufyaan ath-Thawree (d.161H) said: “Innovation is more beloved to Iblees than sin, since a sin may be repented from but innovation is not repented from.” Reported by al-Laalikaa’ee no. 238
Imaam ash-Shaafi’ee (d.204H) said: “That a person meets Allaah with every sin except shirk is better than meeting Him upon any one of the innovated beliefs.” Reported by al-Bayhaqee in al-I’tiqaad pg.158

Al-Fudayl ibn ‘Iyaad (d. 187H) said, “Whoever sits with a person of innovation, then beware of him and whoever sits with a person of innovation has not been given wisdom.

That I eat with a Jew and a Christian is more beloved to me than that I eat with a person of Innovation.” Reported by al-Laalikaa’ee
Al-Fudayl ibn ‘Iyaad (d.187H) said, “Do not sit with a person of innovation. Allaah has rendered his actions futile and has taken the light of Islaam from his heart.” He also said, “Do not feel safe about your deen with a person of innovation. Do not consult him in your affairs and do not sit with him, for whoever sits with a person of innovation Allaah will make him inherit blindness.” And he said, “Verily, Allaah has angels who look for the gatherings in which remembrance is made, so look and see with whom is your sitting. Let it not be with a person of innovation for Allaah does not look at them. And a sign of hypocrisy is that a man stands and sits with a person of innovation.” Sharh Usoolul-I’tiqaad of al-Laalikaa’ee no. 263-265

al-Imaam al-Aajurree mentioned in his Akhlaaqul-‘Ulamaa': “Because from the characteristics of the ‘Aalim al-Aaqil (interllectual scholar) is that he doesn’t sit with ahlul-ahwaa, and doesn’t debate with them” Akhlaaqul-‘Ulamaa’
