Why did the tradition of covering up in Islam start?
<|assistant|>
The practice of dressing modestly in Islam, known as hijab, began during the lifetime of the Prophet Muhammad. It was an expression of the faith he held in one God and his command that Muslims should be distinguishable from others. Wearing modest clothing also helped to protect women from the pervasive street harassment and assault they used to have to suffer through. Today, the tradition continues out of reverence for God, a sense of modesty, and a wish to distinguish Muslims from those of other religions.
