Money Transfer Business

The banks, post office or even the chain stores that offer a money transfer service (for which they charge the client a fee) transfer money for perhaps hundreds of people on a daily basis. We assume that majority of these people have legitimate funds which they are transferring. Yes, we do agree that there always exist a possibility of a few clients transferring illegitimate funds which could be acquired from drug peddling or other ill-legal avenues. If we are uncertain of where the client had acquired the funds from there is no need for us to start speculating and entertaining doubts.

Also, the Ulema have mentioned a principle that if more than 50% of the wealth is acquired from Halaal sources then it will be permissible for one to work at such a company. Therefore, it will be permissible to work for these companies that offer a money transfer service.
