The one who acts without knowledge, destroys and ruins more than he rectifies. - Muhammad al-Jawad

Do not anticipate matters before their time that you may regret. Do not live just with wishes that your hearts may be hard. Be merciful to the weak and ask for mercy from God by being merciful yourselves!

Do not make an enemy of anyone until you know what there is between him and God! If he is good, God will not leave him to you and if he is bad, then your knowing of his badness will make you safe from him and so you do not need to make him your enemy.

Modesty is the decoration of poverty, thanks-giving is the decoration of affluence and wealth. Patience and endurance are the ornaments and decorations of calamities and distress. Humility is the decoration of lineage, and eloquence is the decoration of speech. Committing to memory is the decoration of tradition (hadīth), and bowing the shoulders is the decoration of knowledge. Decency and good morale is the decoration of the mind, and a smiling face is the decoration of munifence and generiosity. Not boasting of doing favours is the decoration of good deeds, and humility is the decoration of service. Spending less is the decoration of contentment, and abondoning the meaningless and unnecessary things is the decoration of abstention and fear of God.
