Alcohol is forbidden because it makes a person loose control. An example of a problem which may arise is having a car accident after drinking and driving. Since alcohol is forbidden to drink, anything which relates to it is also forbidden, such as selling it. But there are many off license stores and pubs owned by Muslims in Britain. RIBA Riba means charging interest.
Islamic law forbids riba.
The reason being that charging someone interest on top of their loan will only make the person stay in debt for a longer period of time. In Britain, banks charge interest most of the time when a customer has a loan. The reason being that they earn profit out of it. As employees, Muslims working in Banks have no say in what their managers decide to do. Therefore, they don t have a choice in charging interest upon customers or not.
