لسان الدين بن الخطيب
Ibn al-Khatib notes that the most outstanding fighter on the Muslim side was Abd al-Malik, Almanzor's son, stressing that this was "by unanimous opinion" without any favoritism and that he excelled even the famous Berber cavalry. Among these, Kayaddayr al-Dammari al-Abra (the Leper), a prince of the north African tribe of the Banu Dammari, was most famous. At Cervera he reputedly decapitated one of the counts of the Banu Gómez and carried his head about with him. Ibn al-Khatib also praises Almanzor's second son by another woman, Abd al-Rahman, who followed his half-brother into battle. Both brothers watched the battle with their father until he finally permitted them, tearfully, to join it.
