What is the definition of “dhilla” (humiliation/abasement) in Islam? Is a Muslim’s work as a cleaner in non-Islamic countries considered a form of “dhilla”? Is society’s view of this work as humiliating considered arrogance? And is there anything in Islam that prevents a Muslim from working in such professions?

The Shari'ah has forbidden argumentation and prohibited a Muslim from working as a servant for a disbeliever, due to the humiliation it entails for the Muslim and the exaltation of the disbeliever. Allah Almighty said: "And never will Allah grant to the disbelievers a way [to triumph] over the believers." (An-Nisa 4:141) If the work is permissible and does not involve humiliation or exploitation, it is unanimously allowed. If it is forbidden, it is unanimously disallowed. Likewise, a Muslim working in cleaning inside the homes of disbelievers or in places where forbidden acts are practiced is not permissible. However, if it is in public places not specifically designated for forbidden acts, then it appears there is no harm in it.
