Is zakat on money obligatory for the entire amount (6000 EGP) if two sums of money are combined (3000 EGP on which previous zakat was due and 3000 EGP new money) and a hawl (lunar year) has passed over both simultaneously, or is zakat due only on the new amount?

The nisab for paper currency is equivalent to the value of 85 grams of gold or 595 grams of silver. Zakat becomes obligatory when the wealth reaches the nisab and a full lunar year (hawl) has passed over it. The amount of zakat is one-quarter of a tenth (2.5%). If the initial amount reaches the nisab by itself or by combining with other funds, zakat becomes due on it after a year has passed. Similarly, any funds acquired during the second year are subject to zakat after a year has passed over them, provided they reach the nisab. At the end of the subsequent year, if the total amount reaches the nisab, zakat is to be paid on the entire sum. If it does not reach the nisab, there is no zakat on it, and anything disbursed from it is considered a voluntary charity.
