The Messenger of Allah (sal Allahu alaihi wa sallam) said: “No man should look at the Awrah of another man and no woman should look at the Awrah of another woman. Also, no man should be with another man under one piece of cloth and no woman should be with another woman under one piece of cloth.” [Muslim]
The Awrah for a man is from his navel to just below his knees. The entire body of a woman with the exception of her face, palms and feet are included in her Awrah in front of a man. In front of another woman, her Awrah is from her navel to just below her knees; though keeping her body well covered and not looking at others’ bodies is more modest and thus more beloved to Allah (subhana wa ta’ala).
