Actors show to people their looks, promote how they can treat females ie buying them gifts etc.
Even Prophet Joseph peace be upon him did not want to end up being stupid, as Males can behave when getting attention from females.
There are lies, for example if an Actor, footballer did not have money, then would they have lots of females wanting to be with them??? No. So do they really like that person for who he is? No? If there was lets say the same female who liked an Actor and she talks about his looks etc, and then what about if the same person did not become and actor, but worked nearby in a meat factory, would this female still like him so much?
The Prophets were good-looking, well-mannered, but people did not like them because of this, of course even people rejected them because they taught people to be good. We did not listen to Prophet Muhammad peace be upon him because he was going to give us presents.
There are I can see, people have the habit of using Males who are not religious as an example of being a Man.
Well I would ask who is better then;-
Prophet Ibrahim peace be upon him?
Prophet Jesus peace be upon him?
Prophet Noah peace be upon him?
Prophet Moses peace be upon him?
Prophet Lut peace be upon him?
Prophet Muhammad peace be upon him?
So we start by looking at the Prophets first, not a singer, actor etc. The Prophets were the best of Men. So makes sense to start using them as examples.
Man = one who worships Allah, remembers the Day of Judgement and in Paradise and Hell.
There has never been any other defintion of being a Man, in worshipping Allah, and he has created us to worship him. The definitions that people use are society ones, wereby they look at being acceptable to others, to gain attention from others. That is poor, as of course in Islam no one can open the gates of Paradise for you, so if you spent 10 years showing off to a group of people, when they cannot help you on the Day of Judgement, then what is they point of showing off to them, when you will not care about them and they neither of you? Of course there is not.
