928 CE to 939 CE
Abbasid caliph Muqtadir feels confident enough in 928 to once again confront Abū-Tāhir Al-Jannābī, son of the late Qarmatian rebel leader Abu Said al-Djannabi, and now ruler of the Qarmatian state in Bahrain, calling in his generals Yusaf bin Abi As'saj from Azerbaijan, Munis Khadim, Muzaffar and Harun.
After a heavy fight, all are beaten and driven back to Baghdad.
Abu Tahir destroys Jazirah Province as a final warning to the Abbasids and returned to Al-Hasa.
Abu Tahir thinks that he has identified the Mahdi as a young Persian prisoner by the name of Abu'l-Fadl al-Isfahani, from Isfahan who claims to be the descendant of the Persian kings, brought back to Bahrain from the Qarmatians' raid into Iraq.
