856 - Al-Duri informed me, saying: Muslim ibn Ibrahim narrated to us, from Ibn 'Uyaynah, from Sa'id, from Simak ibn Harb, who said: I was approached in a dream and it was said to me: "Beware of adultery, beware of theft, beware of consuming the property of the orphan or that which is unlawful, and beware of praying behind al-Hajjaj, for I have sworn that I shall surely break him just as He breaks My servants."
