is recorded to have said that before visiting him in Mashad you should first visit his sister in Qum, and that who ever visits her shall enter Jannat. Masjid al-Jumkaran Hassan Bin Maslah by the order of our 12th IMAM HAZRAT MAHDI A.S built this Masjid. The Imam has said that to pray four rakaat Salaat in this Masjid is equal to the thawab of praying inside Khan al-Ka’aba. It is narrated that Imam Mahdi A.S. visits this Masjid every Tuesday night.
There is a well behind this Masjid and Zuwar write AREEZA asking the Imam to take their Haajat to Allah (SWT) and they put it in this well. Sheikh Saleh (Hassan Maslah Jamkarany) narrates in his book that one Thursday night eve 17th of Ramadhan, and he was sleeping in Jamkaran site (small village) when suddenly he heard someone knocking at the door. He opened it and saw a couple of Sheikhs (clergymen) who after saluting him asked him to follow them, telling him that his master wanted to see you.
He went with them to a place, where Masjid al-Jumkaran (now stands). He saw a throne and a very nice carpet on the floor and a young man of about 30 years of age sitting on it and he was informed that he (the person sitting on the throne) was our 12th Imam A.S. An old man was sitting beside him and was reading a book and more than 60 people in green and white robe were praying around the throne. Later on, he was made to understand that the old man was Nabi Khizr A.S.
Our Imam called Sheikh Saleh by his name and told him to tell the people that they were planting on land, which was not just for planting. They had to pay back all the profit they made from the crops and that with the proceeds they were to build a Masjid on this land. This is a very sacred land and Allah (SWT) picked it from all others. Sheikh Saleh told the Imam that the people would not believe him and the Imam should give him some sign or a letter.
The Imam replied that some kind of a sign at the site would be put till the people would accept his message. So, go and deliver my message to them to build the Masjid from “ardeha” funds from our private property. Tell the people that this is a very sacred place of they should recite four rakaats Salaat.
Two rakaats with the Niyyat of "Tahiyat al-Masjid” and the other two rakaats are for “Imam al-Dhamana A.S.” The Imam further said that each person that recite these four rakaats will get the thawab of reciting inside the Khan al-Ka'aba.
