How can you label women who attend functions to be prostitutes?

Answer

Rasulullah (sallallahu alayhi wasallam) said: "A woman who applies perfume and passes by a gathering is like this and like that (i.e. like an adulteress)." Women who parade in public and mingle with males, and deny the requisites of Purdah/Hijaab, are undoubtedly like prostitutes. It is a befitting appellation for them.
