How is the value of money that has been in an Islamic bank for a full year estimated if its value is not mentioned? Is it permissible to give zakat on money to a brother for the purpose of food and clothing? Is zakat obligatory annually on this money if it remains above the nisab while its profits help with living expenses and you are unemployed?

Zakat is obligatory on monetary assets upon reaching the nisab, complete ownership, and the passing of a lunar year, even if the money is saved. It must be disbursed every year as long as the conditions are met. To determine the amount upon which a year has passed, a bank statement can be requested to identify when the money reached the nisab and to calculate the year from that time. It is permissible to give zakat to a brother if he is eligible, such as being poor or needy, and giving zakat to relatives is more preferable as it is both charity and the upholding of kinship ties.
