Mu’alla, who was a servant of Imam Sadiq (A.S.), narrates the following event:
"One rainy night, as Imam Sadiq (A.S.) left his house, I calmly followed him. Suddenly, something fell out of his hands onto the ground. I approached him and greeted him. He asked:" Is it you Mu’alla?"
"Yes" I replied, "O son of the messenger of Allah (S.A.W.)". He then said:" Touch the ground and hand me what you find." I stretched my hand toward the ground and found a piece of bread.
