What is an example of not combining separate assets for zakat, and what are the types of mixing livestock?

Question : If every household has forty sheep, and everyone who has forty sheep combines them in the eight, their zakat would be one sheep. If they were separate, their zakat would be two sheep.

Answer : One sheep is due on each person. This is combining what is separate. Now, if someone asks how the zakat can be one when it is the wealth of two men? No, no, they are agreed that the wealth belongs to each one individually.
The mixing of livestock is specifically a mixing of entities and descriptions. The mixing of livestock involves entities and descriptions. The mixing of entities is like two people inheriting eighty sheep from their father; this is a mixing of entities because each entity is shared between the man and his partner. The mixing of descriptions is when each one is distinguished, and they share in the matters that the jurists have enumerated.
If the stud, the grazing land, the pasture, the milking, and the shelter are the same, it is certainly a mixing of five things. If they agree on the five things mentioned in this verse, this is a mixing. They have said that the mixing makes the two wealths like one, if the stud, the grazing land, the pasture, the milking, and the shelter are the same, it is a mixing of parts, even if each one of these is distinct.
