Know that God has made zakat obligatory on the generators, which are three metals, a plant, and an animal. The metal is gold and silver, the plant is wheat, barley, and dates, and the animals are camels, cows, and sheep. So he included all the generators and called them generators because they were generated from a mother and a father, from an orbit and its movement, which is in the position of intercourse, which is the father, and the pillars are the mother.
