How did Muslims distinguish themselves from disbelievers in dress during the time of the Prophet, may Allah bless him and grant him peace? And did disbelievers wear long garments? And is loose clothing considered islamically appropriate?

In summary, clothing is a blessing from Allah that covers the awrah (private parts) and protects from heat and cold. The basic principle regarding it is permissibility, as long as it does not violate Islamic conditions. It is forbidden to imitate disbelievers in clothing that is specific to them, such as saffron-dyed garments, which were characteristic of their attire, or the dress of polytheists. However, if a type of clothing is common among both Muslims and disbelievers, there is no harm in wearing it, as the meaning of imitation is no longer present. This is the criterion for forbidden imitation. Clothing that describes or reveals the awrah, or that is worn by men to imitate women and by women to imitate men, is forbidden. It is permissible to wear clothing from disbelievers if its impurity is not known or if it is not specific to them.
