A:
There is nothing wrong if a Muslim is hired to work for a non-Muslim provided that the work they do is known to be Islamically permissible, like building a wall, selling a lawful commodity or any other similar (Part No. 14; Page No. 486) lawful business. This is based on the incident in which
`Aly (may Allah be pleased with him) is reported to have hired himself to bring water from the well that belonged to a Jew in return for some dates. It was reported on the authority of
Ibn `Abbas (may Allah be pleased with him) that
`Aly ibn Abu Talib hired himself as a water carrier for a Jew. He used to take one date for every bucket.
