One of the viziers had a foolish son. He sent him to one of the scholars, saying, 'Educate this one so that he might become wise.' The scholar taught him for a time, but it had no effect. He sent word to his father that this one is not becoming wise and has driven me mad.

When the origin of a gem is worthy

Education will have an effect on it.

No polisher can do a good job

On iron that is of bad essence.

Wash a dog in the seven seas

When it gets wet, it becomes even more impure.

If they take Jesus's donkey to Mecca

When it returns, it will still be a donkey.
