How should a Muslim act who possesses wealth on which zakat is due, but this wealth decreases due to his lack of experience in trade, knowing that Islam has forbidden bank interest and zakat develops wealth?

Zakat (definition) increases wealth and purifies the soul. Allah has made it obligatory on growing wealth that has reached the nisab (definition) and on which a full year (hawl) has passed. Investment of wealth has been legislated so that sadaqah (definition) does not diminish it. If a person is unable to invest their wealth themselves, they should entrust it to those with expertise and religious uprightness. It is impermissible to deposit funds in usurious banks for the purpose of investment, because Allah destroys usury. Instead, it is advisable to purchase real estate that generates regular profit.
