Opening a sewage business
Q: I have recently been thinking about investing in the sewage business. My plan was to purchase two sewage tankers (vehicles) and signing contract with companies that need removal of sewage. The work that I want to do would be completely legal and professional. However someone told me that sewage business is haram in Islam which is why I want to first ask before making any step as I don't want to earn from a Haram source.
