I admonish you regarding five things: if you are wronged, do not commit wrong doing to others; if you are betrayed, do not betray anyone; if you are called a liar, do not be furious; if you are praised, do not be jubilant; if you are criticized, do not fret and think of what is said in criticism.
— Imam Muhammad bin Ali Al-Baqir (a.s.)
