Hakim al-Umma Hadhrat Mawlana Ashraf ‘Ali Thanawi (may Allah have mercy on him) said,

“An innovation (bid’ah ) is to introduce something which has no basis in Shariah (Divine law) into the religion (deen) regarding it to be (an integral) part of religion and to act upon it with the hope of reward.

Indulgence in an innovation is a major sin.”
