One of the verses in Al-Quran states something like this,
"Why did you say things that you are not doing it?"
Let's hear this beautiful story and reflect ourselves, how is our deeds in daily life. Is it increasing, decreasing or still the same one from the day we were being taught by our ustaz and ustazah.
Ya insan, why did you say it, but you are not applying it in your life. You just know how to talk this and that. But the action, none at all.
p/s : a saying goes like this: "Don't judge a book by its cover." But in reality, people's judgment is based on other's external behaviour. If we are looking good externally but 'rotten' inside, then there's no point.
