“The Shia always believed in the uprightness of Uthman Ibn Saeed. His son Abu Ja’far Muhammad Ibn Uthman performed his funeral bath and took the charge and assumed leadership. The Shia were all unanimous on his uprightness, trustworthiness and honesty, due to the explicit narrations pronouncing his honesty and uprightness and commanding the people to refer to him during the lifetime of Hasan (a.s) and after his death during the lifetime of his father, Uthman Ibn Saeed. The Shia did not dispute his uprightness nor did they doubt his honesty. The letters came out through him to the Shia in their important matters during his life. They were in the same handwriting as they were during the lifetime of his father, Uthman. The Shia did not know anyone else, but him in this position. Nor did they turn to anyone else, but him. Many signs and miracles of the Imam, which appeared through him, have been narrated.
