Uthman ibn Sa'id al-Asadi al-Amri (Arabic: عُثْمَان ٱبْن سَعِيد ٱلْأَسَدِيّ عَمْرِوْيّʿUthmān ibn Saʿīd al-ʾAsadīy al-ʿAmrīy) was the first of the Four Deputies, who are believed by the Twelvers to have successively represented their twelfth Imam, Muhammad al-Mahdi, during his Minor Occultation (874–941 CE). Uthman is also said to have been a trusted representative of the tenth and eleventh Imams, Ali al-Hadi and Hasan al-Askari, respectively. The date of his death is not certain, though it is believed that Uthman did not survive al-Askari for long.
