Seyyid Hussein Muddarrisi relates that one of his
female relatives had seen his dead father in a dream.
His father's face was illuminating with light and
beside him was a woman who was folding beautiful and
smart clothes the likes of which she had never seen
in this world before. When asked where the clothes
had come from, the woman replied that they were for
his father and that they had been sent by his sons
for him.
This woman who had seen the dream asked all his dead
father's relatives whether they had done any special
good deeds for their father. One of the Seyyid's brothers
was taken back and admitted that he had prepared for
some clothes to be given to orphans but he had not
actually distributed them.
The Seyyid was so surprised to know that a deed had
been rewarded when only a decision was made on his
part and the charitable act had not taken place yet.
So this proves that any charitable act done for the
dead reaches them immediately, as soon as you make
the intention. (AL QASAS WAL KHAWATIR PAGE 121)
