Can I charge them for this service? In other words, can I tell the customer to enter R205 into the machine while I give him R200 in cash? I will make R5 on the service of giving him the cash. Is this permissible?

Q: I own a manufacturing business where I take orders from customers and manufacture according to their specification. Once their order is prepared, they are notified and given a ten day period to collect the item from our warehouse.

The problem is that many customers delay in collecting their orders. This causes a problem for us as the uncollected orders take up space in the warehouse. In order to avoid this problem, we want to stipulate, at the time the order is placed, that if goods are not collected within ten days, then a stipulated storage fee will be charged for every day thereafter. Is this permissible in Shari’ah?
