which he captured. (1) Al-Fonso (2) then ranged through the farthest Christian territories, rousing every worshipper of the Cross; armies the like of which had never been heard of gathered under his banner. He was reinforced by the Franks of Syria, the troops of Constantinople, and King Arghun (3) of Barcelona.
The sultan likewise summoned the Muslims, and the two hosts met in what came to be called the Battle of al-ʿIqāb. Al-Fonso launched a furious charge that routed the Muslims, and many fell as martyrs.
The chief cause of the defeat was the soldiers’ resentment over the delay in their stipends. The sultan himself stood his ground with absolute steadfastness; but for him his army would have been annihilated. The engagement took place in Ṣafar of the year 609 AH. The enemy returned with spoils beyond description and seized Baeza by storm—To Allah we belong and unto Him we shall return.
A few days later the sultan was struck by apoplexy and died in Shaʿbān, 610 AH, after a reign of fifteen years. He was succeeded by his son al-Mustanṣir Yūsuf, who ruled for ten years.
It is also reported that Muḥammad once went out at night in disguise; the night patrol set upon him and pierced him with their lances while he cried, “I am the caliph! I am the caliph!”
His son:
207 – Abū Yaʿqūb Yūsuf ibn Muḥammad ibn Yaʿqūb al-Muʾminī*
The sultan, al-Mustanṣir bi-Llāh (4), Abū Yaʿqūb Yūsuf ibn Muḥammad ibn Yaʿqūb al-Muʾminī.
