The humane heart of Isabella revolted at the idea of giving up the unfortunate prince into the hands of his most unnatural and inveterate enemy: a disdainful refusal was therefore returned to the old monarch, whose message had been couched in a vaunting spirit. He was informed that the Castilian sovereigns would listen to no proposals of peace from Muley Abul Hassan until he should lay down his arms and offer them in all humility. Overtures in a different spirit were made by the mother of Boabdil, the sultana Ayxa la Horra, with the concurrence of the party which still remained faithful to him. It was thereby proposed that Mahomet Abdallah, otherwise called Boabdil, should hold his crown as vassal to the Castilian sovereigns, paying an annual tribute and releasing seventy Christian captives annually for five years; that he should, moreover, pay a large sum upon the spot for his ransom, and at the same time give freedom to four hundred Christians to be chosen by the king; that he should also engage to be always ready to render military aid, and should come to the Cortes, or assemblage of nobles and distinguished vassals of the Crown, whenever summoned. His only son and the sons of twelve distinguished Moorish houses were to be delivered as hostages. An embassy composed of the alcayde Aben Comixa, Muley, the royal standard-bearer, and other distinguished cavaliers bore this proposition to the Spanish court at Cordova, where they were received by King Ferdinand. Queen Isabella was absent at the time. He was anxious to consult her in so momentous an affair, or, rather, he was fearful of proceeding too precipitately, and not drawing from this fortunate event all the advantage of which it was susceptible. Without returning any reply, therefore, to the mission, he ordered that the captive monarch should be brought to Cordova.
