We are successful to the degree that we are dutiful to GOD, and after that, to how we interact with His slaves. We can easily combine words and embellish our speech to please an audience; the difficult thing is to back up our words with virtuous deeds and a noble character.
A severe punishment awaits a person who orders others to do good without doing it himself, and who forbids others from evil while he perpetrates it himself.

The poet said: “O’ you who are a teacher of others, Would that you had sought first for yourself instruction.”
“An unrighteous man ordering people to righteousness, A doctor treating people while he is sick.”
