The Messenger of Allah said: “Every innovation is misguidance and going astray” Reported by Abu Dawood (no. 4607), at-Tirmidhee (no. 2676) and it is saheeh. Ibn Hajr authenticated it Takhreej Ahaadeeth Ibn ul-Haajib (1/137).

Plus the prophet said: “… and every innovation is misguidance and all misguidance is in the Hellfire.” Reported by an-Nasaa’ee (1/224) from Jaabir bin Abdullaah and it is saheeh as declared by Shaikh ul-Islaam Ibn Taymiyyah in Majmoo’ ul Fataawaa (3/58).

Ibn Taymiyyah said, “Imitating them in outward matters leads to imitating them in attitude and actions, hence we are forbidden to imitate the kuffaar…as it says in the marfu hadeeth: ‘Whoever imitates a people is one of them.’” Majmoo al-Fataawa, 22/154
