Ahmad ibn Muhammad al-Ta'i (Arabic: أحمد بن محمد الطائي; died August 31, 894) was an administrative official in the service of the Abbasid Caliphate.
Ahmad then went to Samarra himself and lured Siddiq with a guarantee of safe conduct, only to seize him, cut off one of his hands and feet, and imprison him and his followers in Baghdad.
[4] In January 889 Ahmad was suddenly arrested and thrown into prison on the orders of the caliphal regent al-Muwaffaq, and according to al-Tabari this event marked the end of his career.
By the time of his arrest, he had been appointed to the governorships of al-Kufah and its Sawad, the Khurasan Road and Samarra, the shurtah of Baghdad, and as revenue official of Baduraya, Qatrabbul, Maskin and some of the private domains of the caliph (diya' al-khassah).
[5] Despite Ahmad's arrest he was apparently soon restored to favor,[6] for in the beginning of the reign of al-Mu'tadid he agreed to a tax farming contract with the central government.
