One day when Imam Reza (a) was on his historical journey from Madina to Marw(Khurasan),while in a jungle the Holy Imam(a) came across a hunter who was about to kill a deer. The deer was trying to get away and when she saw Holy Imam (a), she said something to him.Holy Imam(a) asked the hunter to free the deer so that she could go and feed her little baby deer who were very hungry. Imam Reza(a) also told the hunter that once the deer had fed her babies she would come back. The hunter allowed the deer to go becauseHoly Imam (a) had told him to, but he did not think the deer will come back. But Imam Reza (a) waited with the hunter until the deer returned with her young ones. The hunter was amazed on witnessing this miraculous event and he set the deer free as a mark of respect for Imam Reza(a).After this historical event Imam Reza(a) became famous as Imam Zaamin(a).
