Why do Arabs look down upon sanitation workers, even though this profession is not viewed similarly in the West, but rather is respected and appreciated, despite cleanliness being important in religion and life?

The differing perspectives of societies on the profession of a sanitation worker stem from their customs. The Prophet, peace and blessings be upon him, approved of certain humble professions due to society's need for them. Allah Almighty has made some people subservient to others in various tasks to achieve integration. Islam has encouraged cleanliness and made it part of faith, even viewing the act of sweeping the mosque with reverence. There is no harm in removing harm from the road, home, or mosque, for there is reward in it. However, a Muslim serving a non-believer by cleaning themselves or their home is a humiliation that is not permissible. Imam Ahmad explicitly stated its prohibition, and Ibn Qudamah justified this by explaining that it involves detaining a Muslim at the hands of a non-believer, humiliating them, and exploiting them, which is different from leasing them for a specific task under a contract. Therefore, there is no harm in a Muslim working for a non-believer in a job that involves no humiliation or degradation, and this varies according to the work, society's view, and the worker's need.
