Tezid, son of the caliph Moavias, proved no less unfortunate in his
expedition against Constantinople. His naval force was entirely
destroyed, and that loss compelled him to raise the siege. Among the
Mussulmans who signalized their courage in this expedition, was the
captain Aboux Aioub, one of the companions of Mahomet in the battles
of Bedra and Ohod. He was buried at the foot of the walls of the city.
His tomb is the place at which the Ottoman emperors are girded with the
sword.
