The esteemed scholar, Ahmed bin Muhammad bin Khalid Al Barqi who was present in the life time of Imam Hasan al-Askari (a.s.) and also during the Minor Occultation, says in his book Mahasin:
I was under the patronage of the tax collector of the city of Pahencha Kootkeen. His name was Abul Hasan Madarani. He had given me a yearly endowment, which I used to collect as tax from an area at Kashān, but he was so busy that he became inattentive towards me and my own taxes were demanded from me. I was much worried, when one day a noble and pious man came to me. He was very weak and it seemed as if he had no blood in his body. He was like a walking corpse. He told me, “O Abu Abdillah! There is a relation of common faith and purity between you and me and the relation of devotion to the Pure Imams (a.s.). Please do something for me for the sake of pleasing Allah (S.w.T.) and for the sake of the love of Sādāt.” I asked him as to what he wished? He said, “People have falsely spread the rumour that I have given some secret information against Kūtani to the Sultan. Hence, they have confiscated all my property.”
I promised to help him out and he went away. I thought to myself that if I approached the collector with two requests at the same time I would not be able to achieve them both. On the other hand if I presented the problem of only the old man then what of my own difficulty? I went inside my library and was in deep thought when a tradition of Imam Sadiq (a.s.) came to my mind. It was to the effect that if a person strives, sincerely, to solve the difficulty of a believer, his own difficulty is solved by Allah.” I got up at once and went to Abul Hasan Madarani. When I entered I saw that he was sitting on his chair with a pillow to rest his back and he held a stick in his hand. He told me to sit. At that very moment a Qur’anic verse came to my mind and I recited it loudly:
“And seek by means of what Allah has given you the future abode, and do not neglect your portion of this world, and do good (to others) as Allah has done good to you, and do not seek to make mischief in the land, surely Allah does not love the mischief-makers.” (Surah al-Qaŝaŝ 28:77)
Abul Hasan said that since I have recited this verse I must be in some need? He told me to mention it clearly. I said that people have spread false rumours against such and such person. He asked me if he was a Shia and if he was acquainted with him. I said, “Yes”! He called for the register and I saw that a large property had been seized from the old man. Abul Hasan ordered all the seized property to be restored to its owner. He also told his servants to give him a mule and a new dress and accompany him to his family with respect. After this he said, “O Abu Abdillah you have corrected my mistake.” Then he picked up a slip of paper and wrote an order transferring the rights of the particular piece of land in my name. Again he waited for sometime then ordered the old man to be paid 10,000 dirhams extra, saying, “Because he had guided us to the correct way!”
I requested him to let me kiss his hands but he said that if I kissed his hands he would kiss my feet and said that he did not wish to waste away his good deed. It was nothing much for him as he was holding the rope of the Progeny of Muhammad (S).
