What's the ruling talking to non mahram in public forums, private messages, social medias. Talking casually, talking professionally, talking friendly, talking jokingly, talking teasingly/flirting etc.
does the rule apply to both married ones and none married ones?
for example, can a single Muslim woman talk casually with a non mahram man. Does the same rule apply to the married woman?
by casual talk, basically about everything.
professionally, I mean more in a working environment. Talking to clients etc.
