al-Mansur bi-Allah Isma'il ibn al-Qa'im

Isma'il ibn al-Qa'im, the third of the rulers of the Ubaydid state, titled al-Mansur bi-Allah. He succeeded his father and died at al-Mansuriyya. ¹

Al-Suyuti says that he had the best conduct after his grandfather al-Mahdi, and that he abolished injustices so people loved him. He was succeeded by his son Ma'add, titled al-Mu'izz li-Din Allah. ¹

Ibn al-Athir says he died at the end of Shawwal 341 AH, and that his rule lasted seven years and sixteen days, and that he was thirty-nine years old. He was an eloquent preacher who improvised the sermon for the moment. ²

Ibn al-Athir relates that the cause of his death was a severe cold he caught on a raid, so he was carried to al-Mansuriyya. He wanted to enter the bath-house, and his physician Ishaq ibn Sulayman forbade him, but he would not accept. He says a young man treated him with something that induced sleep, and he slept and was found dead. ² His son Ma'add succeeded him, aged twenty-four. ²

• The details of his death come from Ibn al-Athir alone, and need an additional source.
