Is zakat obligatory on an amount of 2500 euros that was owned on 10 Rabi' al-Awwal 1437? Is this amount considered a nisab? Is it permissible to pay zakat two days or a week before its due date, or to delay it two days after the period due to an excuse? What should one do if they cannot find a deserving recipient for zakat?

For zakat (definition) to be obligatory on banknotes, they must reach the nisab (definition), which is the value of 85 grams of gold or 595 grams of silver. Zakat must be disbursed immediately when it becomes due, unless there is a slight excuse, such as the absence of the poor or the impossibility of delivering it to them. It is permissible to pay zakat in advance up to two years before it becomes due. If there are no poor people in the zakat payer's country, the zakat should be sent to poor Muslims in other countries.
