What is the ruling on the Afghan authorities' imposition of a special dress code for non-Muslims, and is this acceptable in the modern era?

The scholars have unanimously agreed on the obligation for the People of the Book (Ahl al-Dhimma) to wear distinctive clothing or a sign that differentiates them from Muslims. This was affirmed by Umar (may Allah be pleased with him) in the presence of the Companions, and the subsequent Caliphs continued to act upon it. This was done to protect the Sharia (definition) by manifesting the characteristics of Islam and preventing the causes of intermingling that could lead to evasion of religious obligations, to preserve the distinctiveness of the Muslim community and prevent it from imitating non-Muslims, and to differentiate in rulings when applying the laws of the Sharia, especially in matters that non-Muslims are not obligated to observe, such as prayer, fasting, and jihad. The intention behind this is to preserve the identity of the Muslim community, not to diminish non-Muslims.
