Is it permissible to sell food and drink vouchers given to refugees for less than their monetary value?

Bonds whose sale and purchase are prohibited are instruments that include a commitment to repay an amount and interest in return for a loan. As for bonds given to refugees to receive food supplies, they do not fall under the ruling of prohibition, because they are in the category of specific goods and not cash. There is no harm in selling them for their value or less than their value when there is a need for money. However, the default is not to sell them because they are allocated to meet the basic needs of those in need, and selling them may lead to a loss of part of their value and the state's reluctance to provide aid. It is permissible to sell them in cases of urgent necessity, without over-reliance on this option.
