It has been related by Allamah Sayyid Muhammad Al Husayni Al Milaani, that Sayyid Abdullah Al Shiraazi once told him that a young scholar in the city of Najaf once came to the great Marja Sayyid Abil Hassan Al Isfahani, and asked him to give him some money as a help to get married.
The great Marja promised to help him the next day. Now it so happened that within that day the great Marja’s son was assassinated while praying behind his father in the congregational prayer. This incident is famous and well known in Najaf.
The following day during the burial ceremony, the great Marja was seen to be looking around as if searching for someone. His followers thought that he was mentally disturbed since it was an odd behaviour potrayed by the Marja as it was a time of poignant sadness for the Sayyid at the sad demise of his son.
As he kept looking around they saw him calling somebody, and found a young man approaching the Marja and they then saw the Marja give a bag of gold coins to the young man as he had promised to do so, and did not forget this even though he was surrounded with grief. (Qasas Wal Khawatir Page 157)
