Bid‘ahs related to certain nights and days

Q 2: It is a custom here that women engage in playful entertainment from the end of Rajab until the middle of Sha‘ban. They beat the drums, dance, and sing in a loud voice after ‘Isha’ (Night) Prayer from 8 to 10 P.M. What is the ruling on this matter?

A: This is a bad custom and they should not be allowed to do so, for the unrighteousness and unlawful kinds of amusement this involves.
