Section: It is permissible to lease an animal for work, because it is a permitted benefit for which the animal was created, so leasing it is permissible, just as it is for riding. If one leases oxen for plowing, it is permissible; [because oxen were created for plowing]. For this reason, the Prophet (may Allah bless him and grant him peace) said: "While a man was driving an ox, he wanted to ride it, but it said, 'I was not created for this; I was only created for plowing.'" Agreed upon. It requires two conditions: knowing the land and estimating the work. As for the land, it is not known except by observation, because it varies; it may be hard, which fatigues the oxen and the plowman, and it may contain stones that catch on the plow, or it may be soft and easy, making it easy to plow, and mere description is insufficient, so it must be seen. As for estimating the work, it is permissible in one of two ways: either by duration, such as a day or two, or by the land, such as this plot, or from this place to that place, or by measurement, such as a mada or two mada, and the like; all of this is permissible because certainty is achieved thereby. If he estimates it by duration, one must know the oxen upon which he will work, because the objective varies according to their strength and weakness. It is permissible to lease the oxen separately, with the landowner taking charge of the plowing with them. It is permissible to lease them with their owner to take charge of the plowing with them. It is permissible to lease them with their equipment, such as the plow and the yoke, and to lease them without their equipment, in which case the equipment is provided by the landowner. It is permissible to lease oxen and others for threshing crops, because it is a permitted and intended benefit, so it resembles plowing.
