‘Imran b. Husain reported the Prophet as saying, “Having someone to urge on a horse from behind in a race, having a horse beside the one that is being ridden in a race to which the rider may transfer¹, and giving a woman in marriage in return for another without dowry² are not allowed in Islam, and he who plunders does not belong to us.” Tirmidhi transmitted it. 1. Ia jalaba wala janaba. One meaning of the phrase is that expressed in the translation, and is most likely to be the one intended here. Another meaning is that a collector of zakat must notdem and that animals be brought to him from a distance, and people must not remove their animals to a distance when they hear that the zakat collector is coming to them. Cf. p. 375. 2. Shighar.
