SHAFAQNA-Do not dispute (with others) lest you will lose splendor and do not joke (with everyone) lest you will be disrespected.
To greet everyone you pass by and to sit in a place other than the first class of a session are signs of modesty.
Reasonless laughter is a sign of ignorance.
Anger is the key to all evil.
The worst servants of Allah are those who are two faced and two tobgued; they praise their friends and backbite the absent. They envy them for obtaining graces and disappoint them when they suffer a misfortune.
The least comfortable of people is the spiteful.
The heart of a foolish is in his mouth and the mouth of the wise is in his heart.
To show happiness before the grieved is not a sign of good mannerism.
It is very ugly for a believer to follow a passion that causes him humiliation.
Modest is an unenviable favor.
