Dear brother,
Assalamu Alaikum Wa Rahamathulla
A muslim friend of mine intends to start a Laundry & Dry cleaning
business. Can you please clari?

Praise be to Allaah.

There is nothing wrong with doing this kind of work, so long as the
conditions laid down by Sharee’ah are adhered to. These include proper removal of
najaasah (impurities) from the clothes, which may be done using water or by any other
means (according to the most correct opinion), so that no trace of najaasah is left. And
Allaah knows best.
