A Muslim is commanded to observe modesty in general, and specifically to guard his private parts (`Awrah) from being exposed to others. The Shari`ah has clarified what may be exposed of the body—whether male or female—and has defined the boundaries for that.In this Hadith, Mu`awiyah ibn Haydah (may Allah be pleased with him) said: “I said: O Messenger of Allah, with regard to our private parts—what may we expose and what must we conceal?” —meaning: what are we permitted to uncover, and what are we required to keep covered? The `Awrah refers to that which one would feel shame for if exposed. For a man, it is the area between the navel and the knee. For a free woman, it is her entire body. The Prophet (peace and blessings of Allah be upon him) replied: “Guard your private parts” —meaning: guard them from being exposed, or from unlawful intercourse. The first meaning—covering and concealment—is the more appropriate here. “Except from your wife or those whom your right hand possesses” —that is: your wife is permitted to see your entire body, as are the female slaves you lawfully own. This indicates that both marriage and ownership permit viewing each other’s private areas from either side.This Hadith reflects the meaning of the Saying of Allah, the Exalted (interpretation of the meaning): {And those who guard their private parts * Except from their wives or those whom their right hands possess, for indeed, they are not to be blamed} [Al-Mu’minun 23:5–6]Mu`awiyah (may Allah be pleased with him) then said: “I said: O Messenger of Allah, what if the people are gathered closely together?” —meaning: when people are gathered tightly and remain in place, such that we may sometimes be unable to fully cover our `Awrah in the complete and proper way—due to a tight garment or it coming undone due to necessity. So he asked: how are we to manage covering the `Awrah in such situations? And how can we prevent them from seeing us? The Prophet (peace and blessings of Allah be upon him) said: “If you can prevent anyone from seeing it, then do not let anyone see it.” Meaning: protect your private parts to the best of your ability from exposure. Mu`awiyah (may Allah be pleased with him) said: “I asked, ‘O Messenger of Allah, what if one of us is alone?’” Meaning: if a person is in seclusion, with no one else present. It is as though he was asking: is it permissible for a person to remove all of his clothing in such a situation? The Prophet (peace and blessings of Allah be upon him) replied: “Allah is more deserving that one be shy before Him than before people.” Meaning: guard your private parts out of obedience to Him, seeking what pleases Him and earns His approval. The matter is not limited to covering one’s `Awrah only in front of people. What is not intended here is the idea of covering from Allah Himself—Exalted is His Remembrance and His Praise—for such a thing is impossible.Exceptions to exposing the `Awrah include: the time of relieving oneself, while performing ritual bathing (Ghusl), though there is scholarly disagreement concerning this, and in cases of medical necessity, and similar situations in which there is a need. In such cases, exposure must be limited to what is needed, without excess.This Hadith encourages guarding the `Awrah and taking precautions to prevent exposing it in front of anyone other than a spouse or those whom one’s right hand possesses..
