What is the meaning of Bidʻah (innovation in religion)? Is there such a thing as a "good" Bidʻah and a "bad" Bidʻah? What are the consequences for a Muslim who celebrates the Prophet's birthday (Mawlid), knowing that the celebration includes praising the Prophet, mentioning his attributes, reciting the Qur’an and Hadith, supplicating, performing some obligatory prayers, and seeking intercession through the Prophet's status and the status of Surat Al-Fatihah? Is his act considered Haram (forbidden) and does it require repentance?

There is no polytheism (shirk) in the aforementioned celebration, even if it is an innovation (bid'ah). Repentance from it is available through remorse and a firm resolve not to return to it. The presence of some good in such celebrations does not justify them, because Eid (festivals) are part of the Sharia, requiring adherence [to what is prescribed] and not innovation. If celebrating the Prophet's birthday (Mawlid) were good, the predecessors (Salaf) would have done it, for they had the strongest love for the Prophet, peace and blessings be upon him, and were the most eager for good. The perfection of loving and glorifying him lies in following and obeying him and reviving his Sunnah. Many guardians of these innovations are lukewarm in applying what the Messenger of Allah, peace and blessings be upon him, commanded. Some actions may contain good due to their inclusion of permissible elements, and evil due to innovation. The Muslim should be keen on adhering to the Sunnah, inwardly and outwardly, and invite people to it as much as possible.
