Nothing is known about his return to al-Andalus (the Muslim-ruled part of the Iberian Peninsula), nor of any further travel. The memoirs and commentaries of his journey, possibly first presented to the Cordoban caliph Al-Hakam II (961–76), have been lost; only excerpts by later authors have been preserved, principally Abu Abdullah al-Bakri's "Book of Highways and of Kingdoms" and the work of Zakariya al-Qazwini, possibly via the writings of Al-Udri.
