What is the ruling on Zakat for real estate, a fish farm, orange and grape trees, a mother's gold, and a plot of land?

Real estate and land, if intended for trade, are subject to Zakat; otherwise, they are not, based on the Prophet's (peace be upon him) saying: "There is no sadaqah (Zakat) on a Muslim for his slave or his horse."

Fish in a fish farm are considered trade goods; their Zakat is obligatory upon valuation when a year has passed.

Zakat on grapes becomes obligatory if their produce reaches the nisab (five awsuq). Their nisab is one-twentieth if watered with effort, and one-tenth if watered without effort.

There is no Zakat on orange trees.

Gold prepared for permissible personal use is not subject to Zakat according to the majority of scholars, though it is more cautious to pay its Zakat. However, if it is for saving or acquisition, its Zakat is obligatory if it reaches the nisab (approximately 85 grams of pure gold).
