Question: Is celebrating the Prophet’s birthday halaal or haraam?
Response: Establishing the celebration of the Prophet’s birthday or (the birthday of) other than him is an innovation. And it has been confirmed on the authority of the Prophet (sal-Allaahu `alayhe wa sallam) that he said:
((Whoever introduces anything into this matter of ours (i.e. Islaam) that which is not from it, will have it rejected)), [Saheeh al-Bukhaaree/2697 and Saheeh Muslim/1718].
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu `alayhe wa sallam) and his family and his companions.
