What Does It Entail?
Islam has no fixed uniform of dress for Muslim women. But there are two requirements, which come from the Qur’an and hadith (verified sayings of the Prophet Muhammad):
First, a woman’s body should be covered such that only her face, hands, and feet are revealed. Secondly, the clothing must be loose enough so that the shape of a woman’s body is not visible. Other parameters (as stated in hadiths) are that women shouldn’t dress so as to look like men, women shouldn’t dress in a way similar to those who don’t believe in God, and the clothing should be modest, neither ragged nor overly fancy.
It is important to remember that Islam teaches Muslims that the concept of modest dress doesn’t just mean covering the body, but it also has to do with behaviors, manners, speech, and public appearance. Modesty is a total package, with dress being one part of it.
