If it is not proved from the blessed Sahabah رَضِیَ اللّٰهُ عَنْهُم to organize Mahfils [gatherings] of blessed Mawlid and celebrate the day of blessed birth, will it be impermissible to do so?
Answer: place at the blessed birth of the Beloved Rasool صَلَّى اللّٰهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم. (Ma sabata Bis Sunnah, pp. 102)
