It has been related by reliable sources, that a young
man used to serve water to the mourners who came to
the ceremonies commemorating the martyrdom of Imam
Hussein (a.s.).
Once a man who was in the congregation approached
the young man and offered to exchange some cigarettes
in exchange for the spiritual reward the man would
gain due to the good act of charity he was doing.
The young man agreed eagerly being attracted to the
worldly goods.
It so happened that the young man dreamt the same
night, that he was being shown a beautiful palace,
and he is being told that the palace was his spiritual
reward which he exchanged for a few cigarettes. When
he awoke from the dream he bitterly regretted why
he had traded such a beautiful palace for a few cigarettes,
and he knocked on the same night on the door of the
buyer to demand his spiritual reward and to return
the cigarettes.
The buyer refused saying that he had got the same
dream and he was shown the beautiful palace which
was his very own. A quarrel broke out between them
and they had to refer the case to the chief judge
who ruled in favor of the buyer since an agreement
or a contract; be it written or oral cannot be nullified.
