It depends.
-
If I’ve been through the same/similar situation, I would never advice anything that I did not do or wont do if situation comes my way.
-
There are certain things that happened with me but I am going to advise oppositely of what I did in that situations because I realized that my reaction in that situation was wrong.
-
If I can never be in that situation then I will try to give an advice to the best of my ability but I would always have a reason to come up with that advice. (maybe observation or maybe what Islam says on how to deal with such situation etc.)
