Jahiz writes that a woman complained about her disobedient son to his teacher.
She demanded that her son was disciplined by lessons of fear.
The teacher had a very long beard.
He placed it in his mouth, shook his head and began to scream loudly.
This extremely scared the mother.
Frightened she remarked, "I told you to scare the child, not me".
He replied, "You fool, when the punishment of Allah comes, then the good and bad are all destroyed".
