ABSCONDING OF SLAVES Arabic Ibaq إباق. An absconded male or female slave is called Abiq, but an infant slave who leaves his home is termed zall a word which is also used for an adult slave who has strayed. The apprehension of a fugitive slave is a laudable act, and the person who seizes him should bring him before the magistrate and receive a reward of forty dirhams. (Hamilton’s Hidayah, vol. ii. p 278.)
