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.”

Iqtidaa-ul-‘Ilm al-‘Amal By Al-Khateeb Al-Baghdaadee. This is the second book in the "Classical Knowledge Series", which is a collection of selected scholarly works from the past that deal with the subject of religious knowledge. The first book in this blessed series was “The Book of Knowledge” written by Imaam Abu Khaithamah Zuhayr bin Harb An-Nasaa’ee (Died 234H), may Allah have mercy on him. Since that book served as an introduction to knowledge, its virtues, merits and manners, it seemed proper that the second book be dedicated to the next level of knowledge, which is its result and outcome, and that is righteous deeds. And what better work to present on this subject than the classic and well-known treatise of the distinguished Imaam, Al-Khateeb Al-Baghdaadee, 'Iqtidaa-ul-‘Ilm al-‘Amal' (Knowledge Mandates Action).
