Uthman ibn Sa'id al-Asadi

ʿUthmān ibn Saʿīd alʾAsadī al-ʿAmrī (Arabic: عثمان بن سعيد الأسدي العمري) was the first of the Four Deputies, whom Twelver Shia Muslims believe 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 (wakīl or safīr or bāb) of the tenth and eleventh Imams Ali al-Hadi (835–868) and Hasan al-Askari (868–874) respectively. The date of his death is not certain, but most Shia scholars agree that it was in 880-81.
