In "Madinat al Muajiz" it is said that Hazrat Syed al Sajedeen (a.s.) was busy one day in his prayer. Iblees wanted to cause disturbance to the Imam's concentration. He ordered one of his retainers to disrupt the Imam's concentration by causing him bodily harm. The narrator says that the accursed satan came to the Imam in the shape of a big python. We have already mentioned earlier that satans have the faculty to appear in any shape and form they wish to. Anyway, he went near the Imam (a.s.) who was fully absorbed in his prayer. The accursed creature bit one of the toes of the Imam (a.s.). But the pain of the bite was not felt by the Imam (a.s) nor was his concentration disturbed an iota. At that moment a loud sound of Allah's anger was heard and the accursed creature was punished. Then the Herald said, " Anta Zain al abedeen--- verily you are the adornment of the pious ones and the source of pride for them"
