What is the method for paying Zakat on funds collected by charities designated for purchasing housing, what is its monetary amount, and is it permissible to disburse it in the inquirer's country?

The method of paying zakat on employee cooperative funds has been previously explained. The general rule is that zakat should be paid in the country where the wealth is located. There is a difference of opinion regarding transferring it outside the country. Zakat becomes obligatory on wealth once it reaches the nisab (minimum threshold) and a full lunar year has passed over it. The nisab is equivalent to 85 grams of gold or 595 grams of silver. The amount that must be paid is a quarter of a tenth (2.5%).
