Do NOT message me if you are a guy.
I don’t even comment on guys posts now, alhamdulillah. I like a post but keep it to that.
Assalamu alaykum Adding on fb may not be the forbidden khalwah.
Because even Hasan Basri and Rabia Basri are said to hold religious conversations publicly.
But messaging is forbidden khalwah because third party does not know anything which is definition of forbidden khalwah.
