Harith Ibn Abu Shammir, the Ghassanid prince, on his return from Yathrib, commenced a feud with a Jewish poet, who thereby became renowned throughout Arabia. Samuel Ibn-Adiya (born about 500 and died about 560), whose martial spirit was shown in the attacks of the Ghassanids, won immortality through his friendship with the most celebrated poet of Arabia in the time before Mahomet. His biography gives an insight into the life of the Jews of Arabia of that time. According to some, Samuel was descended from the heathen race of the Ghassanids; according to others, he was of Jewish origin, or to be more correct, he had an Arabian mother and a Jewish father. Adiya, his father, had lived in Yathrib until he built a castle in the neighborhood of Taima, which, from its many colors, was called Al-ablak, and has been immortalized in Arabic poetry. Samuel, the chief of a small tribe, was so respected in Hejas that the weaker tribes placed themselves under his protection. Ablak was a refuge for the persecuted and exiled, and the owner of the castle defended those under his roof at the risk of his life. Imrulkais Ibn Hojr, the adventurous son of the Kendite prince, and at the same time the most distinguished poet of Arabia, was hemmed in on all sides by secret and open enemies, and could find shelter nowhere except in Samuel's safe retreat. The Jewish poet, the lord of the castle, was proud to afford a refuge to Arabia's most celebrated writer, whose fame and adventures were known throughout the peninsula. Imrulkais took his daughter and what remained of his retinue to Ablak, and lived there for some time. As the Kendite prince had no prospect of obtaining the assistance of the Arabs to avenge the murder of his father, and to regain his paternal inheritance, he endeavored to win over Justinian, the Byzantine Emperor. Before starting on his journey, he charged Samuel with the care of his daughter, his cousin, and of five valuable coats of mail and other arms. Samuel promised to guard the persons and the goods entrusted to him as he would the apple of his eye. But these arms brought misfortune on him. When the Ghassanid prince was in Hejas he went to Ablak, Samuel's castle, and demanded the surrender of Imrulkais' arms. Samuel refused to surrender them according to his promise. Harith then laid siege to the castle. Finding it impregnable, however, the tyrant had recourse to a barbarous expedient to compel Samuel to submit. One of Samuel's sons was taken outside the citadel by his nurse, and Harith captured him, and threatened to kill him unless Samuel acceded to his request. The unfortunate father hesitated for only a moment between duty to his guest and affection for his son; his sense of duty prevailed, and he said to the Ghassanid prince: "Do what you will; time always avenges treachery, and my son has brothers." Unmoved by such magnanimity, the despot slew the son before his father's eyes. Nevertheless, Harith
