Question
A person has a 50 dinar note and needs to change it into 5 notes of 10 dinars each, so he gave it to someone for that purpose. However, the other person only gave him 30 dinars because he did not have the full amount with him, and he told him that he would complete the rest after an hour. Is this cash transaction permissible? It is commonly and frequently used in grocery and food supply stores.
Answer
I say, and with God's success: Such an action is permissible, and we consider this transaction as a loan for what remains, and for what was paid directly as an exchange, and God knows best.
