Iraq was a nation which in olden times was afflicted
just like any other nation with diseases like cholera
and typhoid, and the epidemic affected so many people.
It is to avert such dangers that the people carried
out many religious ceremonies in the name of the great
Imam and Martyr Hussein (a.s.).
A man relates that in one such ceremony, the people
appealed to Imam Hussein (a.s.) to help them from
such diseases. A man after the ceremony had a dream
that some armed people came to steal things from them.
As they wanted to attempt stealing, the leader of
the gang instructed them to stop because he would
not like to kill people who had taken part in a ceremony
commemorating the martyrdom of Imam Hussein A.S.
The gang leader then asked his companions to go to
another place.
The next morning the man who had seen this dream
heard that, three people had been killed in the neighboring
village by thieves.
All this shows that sadaqa conducted in the name
of our Imams is effective in averting problems. (Najafiat
