What is the ruling on benefiting from the dung of the sacrificial animal according to the four schools of thought, with mention and verification of the references?

The jurists have not provided detailed rulings concerning the dung of the sacrificial animal, except for what is stated in "Al-Fatawa al-Hindiyyah" for the Hanafis: that its dung should be given as charity. However, if the sacrificer feeds the animal, then whatever milk it yields or benefit derived from its dung belongs to him, and nothing needs to be given as charity.

As for matters other than dung, jurists have provided details concerning them, including:

1. Milking the sacrificial animal or shearing its wool: Hanafis: It is disliked to milk the ewe or shear its wool if it has been designated for sacrifice, because it has been designated for an act of closeness to Allah. If this is done, what was milked or shorn must be given as charity. Malikis: It is mildly disliked (makrooh tanzeehan) to drink the milk of the sacrificial animal or shear its wool before slaughter, unless it is known that it will grow back similar wool, or if the intention was to shear its wool at the time of purchase. Shafi'is and Hanbalis: Only the excess milk, beyond what is needed for its offspring, should be drunk from the sacrificial animal. Shearing wool is not permissible unless it harms the animal, and what is shorn must be given as charity.

2. Selling or replacing the sacrificial animal: Hanafis: It is strongly disliked (makrooh tahreeman) to sell a ewe designated for an act of closeness to Allah. If it is sold and the sale is executed, then one must buy an equivalent or better animal for sacrifice. Malikis: It is forbidden to sell a sacrificial animal designated by a vow. It is disliked to replace an undesignated animal with one that is equivalent or lesser. Shafi'is: It is not permissible to sell or replace a mandatory sacrificial animal. Hanbalis: It is permissible to replace a mandatory sacrificial animal with a better one.

3. Selling the offspring of the sacrificial animal: Hanafis: It is disliked to sell the offspring of the sacrificial animal. It must be slaughtered with its mother, or given as charity while alive, or its value must be given as charity if it was sold or consumed. Malikis: It is forbidden to sell the offspring of a sacrificial animal designated by a vow. It is recommended (mandub) to slaughter it with its mother. Shafi'is: If one vows a specific ewe and it gives birth, its offspring must be slaughtered. Hanbalis: The offspring of a sacrificial animal follows its ruling and must be slaughtered during the days of slaughter.

4. Riding or using the sacrificial animal: Hanafis: It is strongly disliked (makrooh tahreeman) to ride or use the sacrificial animal. If this is done and its value decreases, one must give charity equivalent to the value of the decrease. Malikis: The stronger opinion is that it is permissible to lease the sacrificial animal before slaughter. Shafi'is: It is permissible to ride the sacrificial animal and allow others to ride it without charge, with a guarantee if it perishes or its value decreases.
