Is it permissible to deceive in trade in a region like Xinjiang, China, where Muslims are under pressure, and is the statement of some scholars permitting deception and fraud in this case correct?

Deception and fraud are not characteristics of a Muslim. Muslims in other countries are citizens who have rights and obligations, and they have covenants and treaties with the state. The fundamental principle is that a Muslim represents Islam through their ethics and dealings. Cheating non-Muslims and unlawfully consuming their wealth deters people from the path of Allah and discredits the religion. Allah has warned against using oaths as a means of deception, lest one's foot should slip, because a believer's treachery towards a disbeliever causes them to lose trust in the religion and alienates them from Islam. A Muslim should highlight the virtues of their religion and embody them in their conduct and interactions with everyone, inviting them to Islam. The European Council for Fatwa and Research recommends adherence to laws and citizenship rights, and improving the image of Islam.
