What is the ruling on zakat for money that has reached the nisab but has not been held for a full year due to not knowing the duration of stay in the second country and the impossibility of transferring the money? Is zakat obligatory on the owner of the money or on the trustee if he disposes of the money entrusted to him?

Among the rulings regarding Zakat on wealth are: purifying the wealth in the country where it is located at the time the hawl (one lunar year) is completed. If the wealth is moved to another country before the hawl is completed, Zakat is paid in the country where the hawl matured while the wealth was there. It is obligatory to pay Zakat on time, even if one delegates someone else to pay it on their behalf. It is permissible to transfer Zakat from the country where the wealth is located to another country if there is a recognized benefit, or if it is easier for the wealth owner. It is also permissible to pay Zakat in advance, but it is not permissible to delay it if one has the ability to pay it. Wealth deposited in a bank must be purified annually. If the depositor betrays the trust and disposes of the wealth, they are liable to guarantee it. The owner of the wealth must pay Zakat on this wealth for the past years when they receive it, according to the majority of scholars. The more accurate opinion is that they pay Zakat for one year after receiving it.
