It is written in 'Dhillul Mateen' that Meer Mu'inuddin Ashraf who was one of the virtuous attendants of the shrine of Emam Ali- Ar-Reza (A.S.) says that, "Once I dreamd that I was in the shrine of Emam Reza (A.S.) and was coming out to perform ablution (Wuzu). When I came near the mound of Ameer Ali Sher, I saw a group of people entering the shrine. An eminent personality was leading them, and they all carried spades in their hands. As soon as they entered the shrine, the eminent personality pointed towards a particular grave and said, "Dig out the wretched fellow from his grave". Hearing his command they started digging the grave. I asked one of those men as to who that man was. He replied that He was the Commander of the faithful Imam Ali (A.S.). Suddenly I saw that Emam Ali- Ar-Reza (A.S.) came out of His shrine and greeted Imam Ali (A.S.). Hazrat Ali (A.S.) answered His greeting. Emam Reza (A.S.) said, "O my Respected Grandfather! I request you, and have faith, that you will forgive this person on my behalf who lies buried here under the shelter of my shrine". Amirul Mo'mineen (A.S.) answered, "O my dear son! Do you know that he was a mischief-creator, an adulteror, and a drunkard"? Emam (A.S.) replied, "I do know, but when his last moment neared he willed to be buried under the shelter of my shrine, so I request you to forgive him on my behalf." Hazrat Ali (A.S.) forgave him and left. I awoke from my sleep in awe and woke up the other attendants and related to them my dream. We all went to the place which I had seen in my dream, and found a newly constructed grave, whose mud was scattered. After inquiry we learnt that a Turkish man who had died was buried there the day before".
Haji Ali Baghdadi had the honour of meeting Imam Mahdi (A.S.) and ask him some questions. One of the questions put forward by him was that "Is it true that a person who goes for the pilgrimage (Ziyarah) to the shrine of Imam Husain (A.S.) on Friday night receives salvation"? Imam (A.S.) replied, "Yes, by Allah". Haji Ali Baghdadi says that I saw tears in the eyes of Imam (A.S.). Then I asked him another question, "In the year 1269 A.H. when we went for the pilgrimage (Ziyarah) to the shrine of Emam Reza (A.S.), we met a nomadic Arab who was a native of Najaf. We invited him for a meal and asked him his views regarding the reward of the love of Emam Reza (A.S.). He replied, "Paradise", and said, "Since the past fifteen days I have been the ZAIR(pilgrim) of Emam Reza (A.S.), do Munkir & Nakeer' have the nerve to come near me. The food which I consumed from the table of Emam Reza (A.S.) has turned into flesh and blood". I asked Imam Mahdi (A.S.) whether his claim was true. Imam (A.S.) replied, "Yes it is true. Emam Reza (A.S.) himself will come and save him for the questioning in the grave. For verily by Allah! My Grandfather is a Zamin (Surety) Imam".
