al-Ma'mun al-Qadir ibn Dhi'l-Nun

المأمون القادر بن ذي النون

Yahya al-Qadir ibn Dhi-l-Nun, last king of Toledo; famed for the palace whose dome sat in a veil of falling water — until a reciter's verse on the builders-for-eternity foretold his end — then expelled by Alfonso in 478 after a long siege, leaving in the ugliest guise, astrolabe in hand to time his departure, at which 'the Muslims marvelled and the unbelievers laughed' 1.

Overview

Yahya ibn Isma'il al-Qadir billah ibn al-Ma'mun ibn Dhi al-Nun, the last of the Banu Dhi al-Nun in Toledo. 1

The palace and the dome

Al-Maqqari relates from Ibn Badrun that he built a palace in Toledo, the building of which he took pains over, and made in it a pool, and set a dome in its middle. Water was carried to the top of the dome and flowed down around it, so the dome appeared in a veil of continuous water, while he sat inside it and the water did not touch him. 1

The report says that he heard a reciter recite a verse that the builder does not live forever, and not long after he died. The passage here is about the building, not about who died; this needs an additional source. 1

The fall of Toledo

Alfonso besieged Toledo and took it from him in 478 AH, after a long siege that is said to have lasted seven years. He left it carrying an astrolabe with which he fixed a time for departure, and the Muslims marvelled at him and the unbelievers laughed at him, in al-Maqqari's phrasing. 1

Toledo

Toledo, the Gothic capital of al-Andalus on the Tagus; Tariq ibn Ziyad took it and seized there the great table Musa ibn Nusayr presented to al-Walid at Damascus in 96. Ibn Khallikan's famous tale: each Gothic king added a lock to a sealed house until Roderic, the twenty-seventh, opened it and found only a scroll and painted Arab horsemen, prophesying that whoever opened it would see those pictured men enter al-Andalus.
