God Almighty commanded the Muslims to take out a part of the money that He provided them with, and made them entrusted in it, and made this one of the five pillars of Islam.
When gold reaches the nisab, which is 85 grams or more, and a year has passed, then the nisab must be calculated and a quarter of a tenth of it, i.e. 2.5%, should be taken out.
It is the flipping of money for the purpose of profit. Zakat on trade money is due at the end of the year, by evaluating it with the two currencies with which you bought (gold and silver) or something equivalent to them.
If he takes his shares for trading, buying and selling, then the zakat due on them is a quarter of a tenth (2.5%) of the market value on the day zakat becomes due, like all other trade offerings.
Zakat is obligatory in the original deed only, but usurious interests must be disposed of, and according to the decision of the Shariah Board, the Permanent Committee, and seminars on contemporary issues of Zakat.
Zakat must be given if it is what he eats and saves. Its nisab is equal to 653 kilograms, and there is no zakat on less than that, and it includes one-tenth if it is irrigated with sky water, and one-half of one-tenth if irrigated with sprinkling and the cost.
Zakat on livestock includes cattle, camels, and goats ( Sheep are deemed as goats). Zakatable livestock becomes obligatory only when one owns a specific number of heads in order to reach Nisab
