Islamically, a dress is supposed to serve two purposes:
1. Covering the `Awrah (private parts) of the body.
2. Serving the purpose of adornment and beautification.
Reviewing the Qur’an, we find that Allah, the Almighty, describes the dress of believers as “The Dress of Piety” or Libasut-Taqwa, and this exactly emphasizes the aforementioned two conditions, and stresses that such a dress should never be used for showing off. Almighty Allah says: “But the raiment of righteousness, - that is the best.” (Al-`Araaf: 26)
Islam has provided few guidelines to achieve this quality:
1. The first condition is that the dress has to be Halal by its origin, i.e. purchased or owned through Halal earning.
2. The second is that it must not imply imitation of other people’s dress. This means we should not imitate others’ religious attire or style, as the Hadith states: “Whoever imitates some people will be ranked among them.” (Irwaa’ul Ghaleel, Al-Albaani, Hadith no. 2384)
3. The third condition is that the dress must not carry any resemblance to women’s dress. This means men’s dress must not involve any kind of feminine style of adornment: pure silk, golden dress, very bright and fast color, are all considered permissible for women, but not for men.
Below this level are some cultural choices and this may come as a second level. But what is important is that Islam promotes unique identity for Muslims in every action, and this applies to the dress code. So, Islam encourages the dress which represents the message of Islam, and which distinguishes Muslims from others.
