It has been related in the book ‘Al Irshadaat fi ilm il Ibaadaat’, that a man prayed for a dead woman and this woman came in his dream to thank him and assure him that his prayers had reached her in the form of blessings.
It has been related in the book stated above that a woman used to work in somebody’s house. The owner of the house had invited some guests and shortly after the guests had left, the maid servant collected all the remaining food and gave it as Sadaqah in her mother’s name.
The next day the maid was visited by her sister who informed her that she had dreamt their deceased mother who informed her that the food her sister had sent had reached her, but she had asked that the next time she should send proper Sadaqah and not remains of some meals.
Sheikh Sudooq relates from Imam Ja’far Sadiq who heard this tradition from the Holy Prophet Muhammad (S) that once Prophet Isa (a.s.) was passing a grave whose occupant was being tortured. After some time, Nabi Isa (a.s.) passed that grave again and saw that the torture had stopped.
He asked Allah who revealed to him that the deceased’s son had given charity and so the torture had stopped.
After the death of Ayatullah Sayyid Mirza Mahdi Shirazi, a believer saw him in the dream and asked him: “What was the act he really benefited from in the Akhira”.
The great scholar replied that it was small acts of charity he had given to beggars who knocked his door and were satisfied with whatever was given to them.
