he said to abu al-Hassan (a.s.) the following. “We narrate from abu ‘Abdallah (a.s.) that he has said, ‘Our knowledge consists (of the knowledge of the things) of past, of the written nature, that which is dotted in the hearts and that which is struck against the ears. He then said, “As for that about the matters of the past is that which is passed our knowledge. That which is written is the kind that will come in future. That which is dotted into the hearts is the inspired kind and that which is struck against the ears is the order of the angel.”
