till the year 430.” [1] Mawaqidul Maarif, 2/63 Shaykh Tusi further says, “The Governor, Muhammad bin Faraj had a metal enclosure constructed over the grave of Uthman bin Saeed and the neighbors and people visit the grave and obtain blessings therefrom.” [1] Condolence of the Awaited Imam (a.s) After the death of Uthman bin Saeed, His Eminence, Imam Mahdi (a.s) sent condolence letter to his knowledgeable son, Muhammad bin Uthman as follows: “Indeed we are from Allah and to Him we shall return...We submit to His command and are satisfied with His decree.
Your father has lived in good fortune and has passed away with dignity. May Allah's mercy be upon him, he has joined his friends and masters. Your father was always in the affair of the Imams (a.s) and whatever would bring him near to Allah. May Allah brighten his countenance! May Allah give you more reward...and from the success of that departed one it is sufficient that he had a son like you, who would succeed him in his place and invoke mercy for him.
And I also say that thanks be to my Lord because the hearts of the Shias are happy because of what Allah had made in you. May Allah help you and make you succeed. May He be your guardian and protector.” Just as the sorrowful statements of His Eminence, the Master of the Age prove the trustworthiness and elevated status of Uthman bin Saeed, in the same way they confirm the reliability and trustworthiness of his son, Muhammad bin Uthman, who also possessed great merits and good manners...
[1] Moraqidul Maarif, 2/63 2. Muhammad bin Uthman After the death of his father, Muhammad bin Uthman succeeded to the post of the special deputyship of the Awaited Imam (a.s). Muhammad was among the trustworthy and reliable persons and was a dignified personality of the Shias in his knowledge as well as his actions. Since everyone also trusted him like his father, the Shia people now forwarded their queries and religious payments through him to the Holy Imam.
Muhammad bin Uthman then conveyed the replies of the Imam to his Shias. Justice and Trustworthiness of Muhammad bin Uthman All biographers of Muhammad Ibne Uthman are unanimous about his work, position and elevated status among the Shias. And this distinction is sufficient for him that he was a special deputy of the Proof of Allah, and the Awaited Imam (a.s). A position held by his father during his lifetime, which after his passing away was transferred to Muhammad Ibne Uthman.
