The sign of the merciful person is calmness, serenity, tolerance, open-mindedness, patience, gentleness, wait, self-examination before rushing into the reactions, abstaining from fighting on immediate fortunes and self benefits, refraining from grudge, controlling desire, long thinking, love of silence and enjoying being alone. That is because the merciful person has light inside himself that makes him feel comfortable despite being alone; that is because he is in constant dialogue with Allah, and permanent ease with the creation.
