said to a friend that I have chosen rather to be silent than to speak because on most occasions good and bad words are scattered concurrently but enemies perceive only the latter. He replied: ‘That enemy is the greatest who does not see any good.’

The brother of enmity passes not near a good man
Except to consider him as a most wicked liar.
Virtue is to the eyes of enmity the greatest fault.
Sa’di is a rose but to the eye of enemies a thorn.
The world illumining sun and fountain of light
Look ugly to the eye of the mole.
