How is Zakat on wealth calculated when there is money mixed with usurious gains and a scholarship, and is it a condition for the recipient of Zakat to be a نماز-performer, or is it sufficient for them to outwardly appear Muslim?

The Nisab (minimum threshold) is the lowest amount upon which Zakat becomes obligatory. It varies depending on the type of wealth: for camels, it is five; for gold, it is 85 grams; for silver, it is 595 grams; and for money, it is the equivalent value of either of these two Nisabs.

For gold, silver, and money, the completion of one lunar year (Hawl) is a condition for Zakat to become obligatory. Zakat is paid at a rate of one-quarter of one-tenth (2.5%), which is calculated by dividing the amount by forty.

The recipients of Zakat are specified, and it is not sufficient for a beneficiary to merely be a Muslim. It is also not a condition that the Zakat recipient be righteous and pious; rather, it is permissible to give it to a poor transgressor.

Usurious interest (Riba) is not subject to Zakat, and one must dispose of it by spending it on the welfare of Muslims or giving it to the poor and needy. It is not counted as part of the principal capital. A Muslim should strive to gain a deep understanding of their religion.
