According to the Holy Quran, covering and Hijab of body dates back to the time of Adam and Eve in the Garden of Eden: “So when they tasted of the tree, their nakedness became exposed to them, and they began to stitch over themselves with the leaves of paradise.” (7:22). This demonstrates that following the standards of modesty is innate in all human beings, and so do the Islamic dress codes.

 Since modesty as the reason to wear the Hijab in Islam is a subjective term, the Quran and Sunnah have laid out the bare minimum to prevent any confusion. The absolute minimum covering in Islam set for men is loose and unrevealing clothing from his navel to his knee . Men are not allowed to wear gold jewellery, silk clothing, or adornments that are considered feminine.
Muslim women, like men, are not permitted to wear tight and revealing clothing; especially the ones showing the details of their body. The clothing should cover their hair and body.
