Hamzah ibn al Tayyar was reproducing some of the speeches of the father of Abu `Abd Allah (i.e. al-'Imam al-Baqir [A]) in his presence. When he reached a point the Imam (A) said: "Stop and be silent." Then he added, "When something comes to you that you don't know, your duty in such a case is nothing but to halt, to verify it and refer it to the Imam of guidance (a'immat al-huda), who will lead you to what is right, clarify that which was obscure for you and acquaint you with the truth therein. God Almighty has said:
`ask the family of the reminder, if you know not."' (16:43)
`ask the family of the reminder, if you know not."' (16:43)
