was buried in Rusafa, at a mausoleum he had erected across from the tombs of his father, al-Muti', and of his great-grandmother, the mother of al-Muqtadir, Shaghab. Al-Ta'i's deposition had a long denouement: considering al-Qadir a puppet of the Buyids, the eastern dynasties of the Samanids and Ghaznavids refused to recognize the succession until 999/1000, continuing to use al-Ta'i's name in the Friday prayer and on coins until then. Furthermore, a relative of the deposed caliph, Abdallah ibn Ja'far, managed to escape custody in Baghdad and fled to Gilan, where he persuaded the local ruler that he was indeed al-Ta'i'. Only after Baghdad found out about this pretender was his true identity revealed.
