Installing urinals on one's premises
Q: My father built a new building for his business; I noticed that urinals were installed in the employee bathrooms. When I asked my father, he said that not everyone is a Muslim and that these urinals are for his non-Muslim employees.
1. Is it permissible to install urinals in one's office building, supermarket, shop etc.?
2. Is it permissible for a Muslim plumber to install a urinal?
