It was narrated that Hudhaifah said: "The Messenger of Allah (ﷺ) said: 'Allah will not accept any fasting, prayer, charity, Hajj, 'Umrah, Jihad, or any other obligatory or voluntary action from a person who follows innovation (Bid'ah). He comes out of Islam like a hair pulled out of dough." (Maudu')

It was narrated that 'Abdullah bin 'Abbas said: "The Messenger of Allah (ﷺ) said: 'Allah refuses to accept the good deeds of one who follows innovation until he gives up that innovation.'"
