Be dignified, honest and truthful.
Acquire knowledge before you become leaders and pride prevents you from learning and you live in ignorance.
Do not overeat; that invites disease.
If Allah wants for a people ill, he gives them debates and takes away from them actions.
That which you do not wish for yourself, do not impose on others.
The happiest of people is the one under whose care people are happy because of him, and the most miserable of people is the one under whose care people are miserable because of him.
