Answer
The concept of Moulood (celebrating of the birth of Nabi (Sallallaahu Alayhi Wasallam), has no basis in Shari?ah. Listening to a talk about the life of Nabi (Sallallaahu Alayhi Wasallam) is indeed a virtuous act.
This virtuous act, however, must not be associated with any un-Islamic factors, for example, intermingling of sexes, etc.
