How is the Zakat on money invested in land shares, whose principal and profits have not been returned, to be paid, considering that the time for paying Zakat is Ramadan of every year, and the Zakat on this money was not paid in Ramadan 1422 AH and 1423 AH?

If you have invested in lands with the intention of awaiting profits, these lands are considered trade goods, and zakat is obligatory on them every year. One-quarter of one-tenth (2.5%) of their market value must be given, provided their value reaches the nisab. You must also pay zakat for the previous years that you did not pay, using the same method.
