Question 218: Is it permissible to celebrate religious ‘Eeds (festivals), such as the Mawlid (the Prophet’s birthday) or the 15th night of Sha‘baan, as the case may be?
Answer: (a) It is not permissible to celebrate innovated ‘Eeds.
(b) The Sunnah prescribed only two ‘Eeds in Islaam, i.e. ‘Eed-ul-Ad-haa (the Festival of the Sacrifice) and ‘Eed-ul-Fitr (the Festival of Breaking the Fast). During these two ‘Eeds, it is prescribed for Muslims to rejoice, show happiness, and perform the rituals that Allaah (Glorified be He) has ordained during them, such as Salaat-ul-‘Eed (the Festival Prayer) and the like. But it is unlawful to practice any Haraam (prohibited) matters.
(c) It is not permissible to celebrate the birth of the Prophet (peace be upon him) or that of any other person. The Messenger of Allaah (peace be upon him) did not celebrate his birthday nor did he enjoin Muslims to do so. Likewise, the Sahabah (Companions of the Prophet, may Allaah be pleased with them) did not celebrate the birth of the Prophet (peace be upon him) and neither did the Salaf (righteous predecessors) in the three best generations of Islaam. Indeed, all goodness lies in following their way.
(d) Celebrating the 15th night of Sha‘baan is a Bid‘ah (innovation in religion) and so is the celebration of the 27th night of Rajab, which some peoplecall the Night of Israa’ (Night Journey) and Mi‘raaj (Ascension to Heaven). Allaah is the One sought for help… read more here.
