The Prophet sal Allaahu alayhi wa sallam also warned us against innovation. As he said in one hadith: "Whoever innovates in it or supports an innovator, then the curse of Allah and the curse of the angels and the curse of all of mankind will be upon him (Allah will not except from him any good deed).”
A decimation upon the innovated celebrations prevalent amongst the Muslims, and an elevation of the true Islamic celebrations according to the authentic Sunnah.
