A reliable gentleman has narrated this incident, although this report is famous among the people of Najaf Ashraf. The incident is as follows: The house in which I reside, in this year 789 A.H., once belonged to a virtuousand pious man named Husain Mudallil and Sabaat Mudallil is named afterhim. And this Sabaat (a roof between two houses) is adjacent to the walls ofthe Holy mausoleum of Najaf. This person also had a family.
He became affected by such terrible paralysis that he could not evenstand up. The members of his family used to assist him in fulfilling hisnecessary needs. He remained affected by this malady for a long time as aresult of which his family had to face penury and to depend on charity.
In 720 A.H. when a quarter of the night had passed, he awoke his family members. They saw that the house and the ceiling were illuminated with sucha bright light that it dazzled the eyes. They asked him what the matter was. He said: The Imam of the Time (a.s.) had come and he told me: O Husain, stand up. I said: My master, I am unable to stand up as you can see. He took my hand and made me stand up and all the signs of paralysis disappeared. Now I am perfectly healthy and cured.
The Imam (a.s.) also said: This canopy is my route to visit mygrandfather, Amirul Momineen (a.s.) so you must close it every night. I said: We hear and obey Allah and you are our master! After that the man arose and
by way of thanksgiving for this divine mercy and kindness he went to visit the mausoleum of His Eminence, Amirul Momineen (a.s.). And that canopy, till this day is a place where people pray during times of need and all those who make petitions at this spot achieve success by the blessings of the holy footsteps of the Qaim (a.s.).”
