The Islamic definition of Bid’ah: Imaam Ash-Shaafi’i, may Allah have mercy upon him, said: “A Bid’ah is anything that has no basis in the Qur’aan, Sunnah or sayings of any of the companions.” Ibn Al-Jawzi, may Allah have mercy upon him, said: “A Bid’ah is any form of worship that did not exist (at the time of the Prophet sallallaahu ‘alayhi wa sallam and his companions) then later it was innovated.” Ibn Rajab, may Allah have mercy upon him, said: “A Bid’ah is any form of worship which has no basis in the Sharee’ah which would warrant its legislation.”
