The Just Leader of Humanity 6
In addition to these favorable statements from the Imams accrediting 'Uthman b. Sa'id, there are miraculous acts (karamat) ascribed to him. These acts actually provide further evidence to bolster the truthfulness of his statements. For instance, Shaykh Tusi in his Kitab al-Ghayba, relates the following story from a number of persons belonging to Nawbakht family, including Abu al-Hasan Kathiri:
A person brought some goods [belonging to the twelfth Imam] from Qumm and the vicinity to 'Uthman b. Sa'id. When the person wanted to leave 'Uthman b. Sa'id said: "You have been entrusted with something else too. Why have you not delivered it?" The person said: "There is nothing else left." 'Uthman b. Sa'id told him to go back and search for it. After a few days of searching the person returned to report that he had not found anything on him. At that 'Uthman b. Sa'id asked him: "What happened to the two pieces of cloth that were handed to you by so and so?" The person said: "By God, you are right. But I have forgotten about them, and now I do not know where they are." Once more he returned to his place and searched for the material, but could not find it. He came and told 'Uthman b. Sa'id about that. 'Uthman said: "Go to so and so, the cotton seller, to whom you delivered two bundles of cotton. Open the bundle on which such and such is written. You will find that entrusted material in it." The man went and did what 'Uthman b. Sa'id had asked him to do. He found the material and brought it to him.
Muhammad b. 'Ali Aswad, another agent of the Imam, was given a piece of cloth by a woman for 'Uthman b. Sa'id. He took it with some other clothes to 'Uthman. 'Uthman asked him to hand it to Muhmmad b. 'Abbas Qummi. He did so. After that 'Uthman b. Sa'id sent him a message which said: "Why have you not delivered the cloth given by the woman?" Muhammad b. 'Ali Aswad remembered the cloth and searched for it until he delivered it to him.
Shaykh Saduq has narrated another incident in his Kamal al-din. He writes:
A man from Iraq brought the Imam's share (sahm imam) to 'Uthman b. Sa'id. 'Uthman returned the money and said: "Deduct from it that which you owe to your cousins." The man was surprised to hear that. When he investigated his goods he found that he owed part of the agricultural land to his cousins, which he had not returned. On careful calculation he found that the land was equivalent to four hundred dirhams. Thus, he deducted that from his goods and took the remaining portion to 'Uthman b. Sa'id. This time it was accepted from him.
After all these reports about 'Uthman b. Sa'id's honesty and trustworthiness, the respect with which he was held by the tenth and eleventh Imams, and the consensus among the Shi'a about his moral probity and sound character, is it fair to assume that he was a manipulative individual, intent upon deceiving the generality of the Shi'is?
Muhammad b. 'Uthman, the Second Deputy
Muhammad b. 'Uthman succeeded his father, 'Uthman b. Sa'id, as the deputy after the latter's death in 260 AH/874 CE. Shaykh Tusi, commenting on both these deputies of the Hidden Imam (peace be upon him), writes that "they enjoyed the highest esteem in the eyes of the Master of the Age."
According to Mamqani, the high status of Muhammad b. 'Uthman among the Shi'is is self-evident. They are in agreement that during the lifetime of his father he was the deputy of Imam Hasan 'Askari, and later on he became the deputy of the twelfth Imam. In fact, 'Uthman b. Sa'id explicitly appointed Muhammad b. 'Uthman as his successor and the deputy of the Hidden Imam.
Ya'qub b. Ishaq, a prominent follower of the Imams in Samarra, relates:
