All human beings are limbs of the same body. God created them from the same essence. If one part of the body suffers pain, then the whole body is affected. If you are indifferent to this pain, you cannot be called a human being.
SaadiWhoever recounts to you the faults of your neighbour will doubtless expose your defects to others.
SaadiNo one ever sowed the grain of generosity who gathered not up the harvest of the desire of his heart.
