مُحَلِّلٌ
1.
2.
In a case of racing, (assumed tropical:) He that intervenes between two contending for a stake or stakes, (S,) or the third horse in a contest for a stake or stakes; (K;) if he outstrip, he takes [the stake or stakes]; and if he be outstripped, he is not fined: (S, K:) the case is this: two men lay two stakes; and then another comes, and starts his horse with the two others, without [laying] a stake; if one of the first two outstrip, he takes the two stakes, and this is lawful because of the third; but if the مُحَلِّل outstrip, he takes the two stakes; and if he be outstripped, there is no fine for him: he must be a horse of which one is sure that he may outstrip; otherwise it is termed قِمَارٌ: and he is also called دَخِيلٌ: (TA:) the مُحَلِّل in racing is so called because he makes lawful the contest for a stake or stakes, which had otherwise been unlawful.
